The QTR9090200 managed trend has a target of 1.5 and a cost of 16 basis points. The strategy involves eight fixed exchange-traded fund sleeves, each starting with $1250, and independently reinvesting cash. The initial weights are equal, but they can drift over time without monthly rebalancing. A new position is entered at the next session's open if the prior 252-session close return is positive. The strategy does not use shorts or leverage. A stop-loss is set at 1.5 times the prior 20-day mean high-low range, and a breakeven stop is set at the prior high plus 1 times the range. If the market gaps against the position, the stop-loss takes priority. The target is filled conservatively, and there is no reentry in the same month. The position is liquidated at the end of the month. The strategy was trained on data from 2017 to 2020, and tested on data from 2021 to 2025, with an extension from January to August 2026. The fees are 1 basis point plus 15 basis points for slippage on each side. The results show a return of -4.191249393480845 in 2026. The simulated portfolio returns are based on completed trades only and do not include partial current month returns. The data used is proxy data and does not include futures excess returns, inverse-volatility scaling, or original long-short paper replication. The research is based on prior work and not on untouched prospective evidence. The conclusion is to reject venue-style transfer and report fixed variants without selecting the best. The sources used include https://runway.adityaperswal.workers.dev/data/stock-bars?feed=sip&adjustment=all and https://w4.stern.nyu.edu/facdir/lpederse/papers/TimeSeriesMomentum.pdf, as well as the QTR9090200 research and archived results.
The QTR9090200 managed trend has a target of 1.5 and a cost of 6.000000000000001 basis points. This trend is based on eight fixed exchange-traded fund (ETF) sleeves, which are investment funds that trade on a stock exchange like stocks, with each sleeve starting at $1250. The cash from these sleeves is reinvested independently, and their initial weights are equal, but they can change over time. A new investment is made at the start of the next session if the previous month's return was positive. The investment strategy does not involve short selling, which means betting against a stock, or using leverage, which means using borrowed money to invest. The strategy includes a stop-loss order, which is an order to sell a stock when it falls to a certain price, set at 1.5 times the risk. If the stock price goes up, the next day's entry price will be the previous high plus 1 times the risk. The strategy prioritizes stopping losses over making gains if the stock price gaps down at the open. The target is to make a conservative gain. The investment is liquidated at the end of the month and cannot be re-entered in the same month. The training data for this strategy is from 2017 to 2020, and the testing data is from 2021 to 2025, with an extension from January to August 2026. The warm-up period is 2016, and no missing early history was invented. The fees are 1 basis point plus 5 basis points for each buy and sell, which is a type of trading cost. The results show a return of -2.7706881044148424% in 2026. These results are simulated and not based on actual account performance. The trades are based on completed months only and do not include partial months. The data used does not account for 15-minute venue exits, gap overshoot, or National Best Bid and Offer (NBBO) prices, which are the best prices at which to buy or sell a stock. The sizing of the investments is fractional, and there are no fixed business costs. The ETF adjustment means that all returns are proxy data, which is substitute data used to represent the actual data, and not actual futures excess returns, inverse-volatility scale, or original long-short paper replication. The era used in this research has been used before and is not new, untouched evidence. The conclusion is to reject transferring this strategy to a different venue, and the fixed variants are reported without selecting the best one. The sources of the data are https://runway.adityaperswal.workers.dev/data/stock-bars?feed=sip&adjustment=all and https://w4.stern.nyu.edu/facdir/lpederse/papers/TimeSeriesMomentum.pdf, and the research is based on the QTR9090200 research/trend.py and archived results.
A news scan found the headline about QTR9090200 recent parent trend with a 252 target and 1.5 cost at 16 basis points. The details are as follows: the fund has eight fixed exchange-traded fund, or ETF, sleeves that start with 1250 USD each and reinvest cash independently, with equal initial weights that can drift over time without monthly rebalancing. The fund enters a position at the next session's open if the prior month's 252-session close return is positive, without using shorts or leverage, and holds it until the last session of the month without a managed stop or target. The fund does not reenter a position in the same month and liquidates at the end of the month. The training period is from 2017 to 2020, with a holdout period from 2021 to 2025, and an extension from January to August 2026, with a warmup period in 2016. The fees are 1 basis point plus 15 basis points for slippage on each side of a trade.

This is a test of a managed trend strategy called QTR9090200. The strategy has the following rules: it starts with eight fixed exchange-traded fund, or ETF, sleeves, each with an initial investment of 1250 USD, and it reinvests any cash earned, but it does not rebalance the sleeves every month. The strategy only buys, or goes long, and does not sell short or use leverage, which means using borrowed money to invest. It enters the market at the start of a session if the return from the previous 252 sessions is positive. The strategy uses a stop-loss order, which is an order to sell when a stock or fund reaches a certain price, in this case, the average high and low prices from the previous 20 days, and it aims to make a return of 1.5 times the risk, or R. If the strategy makes a profit, it will close the position at the next session's open, and if it loses, it will stop the loss at the prior high price plus 1R. The strategy does not re-enter the market in the same month and liquidates its positions at the end of the month. The strategy was trained on data from 2017 to 2020, tested on data from 2021 to 2025, and extended to August 2026, with a warm-up period in 2016. The strategy charges a fee of 1 basis point, or 0.01 percent, plus a slippage fee of 15 basis points, or 0.15 percent, for each buy and sell order. The results of the strategy are as follows: in 2021, it lost 3.373370323894198 percent, in 2022, it lost 0.777860349589854 percent, in 2023, it lost 3.264245863495463 percent, in 2024, it lost 3.944768809858712 percent, and in 2025, it lost 2.5341718390499146 percent. These results are simulated, not actual, and are based on completed trades only. The strategy uses daily high, low, open, and close prices, but does not account for 15-minute venue exits, gap overshoot, or national best bid and offer, or NBBO, prices. The strategy also uses proxy data, not actual futures excess returns, inverse-volatility scale, or original long-short paper replication. The data used for this strategy comes from the following sources: https://runway.adityaperswal.workers.dev/data/stock-bars?feed=sip&adjustment=all and https://w4.stern.nyu.edu/facdir/lpederse/papers/TimeSeriesMomentum.pdf, and the code for the strategy is available at QTR9090200 research/trend.py and archived results.
A news scan found the headline about a test of a managed trend. The test, called QTR9090200, has a target of 1.5 and a cost of 6.000000000000001 basis points, which is a measure of the cost of buying or selling something. The test started with eight fixed exchange-traded fund, or ETF, sleeves, each with an initial value of 1250 USD. An ETF is a type of investment that is traded on a stock exchange. The test reinvested any cash that was made, but did not rebalance the sleeves every month. The test only bought, and did not sell short, which means selling something that the seller does not own. The test used a stop-loss, which is a rule to sell something when it loses a certain amount of value, and a target, which is a price at which to sell something. The test stopped buying if the price went below a certain level, and did not buy again in the same month. The test ended at the end of each month. The test was trained on data from 2017 to 2020, and tested on data from 2021 to 2025. The test had fees of 1 basis point, plus a slippage of 5 basis points, which is the difference between the expected price and the actual price. The results of the test were -1.9505770967010672 in 2021, 0.15055079111834235 in 2022, -2.1492579088145836 in 2023, -2.13749270260134 in 2024, and -0.5190949031960157 in 2025. These results are simulated, which means they are based on historical data, and not actual. The test used data from a website, and a research paper. The test concluded that it should not be transferred to a different venue, which is a place where something is bought or sold.
A news scan found the following text: QTR9090200 is a test of a parent trend with a target of 1.5 and a cost of 16 basis points. The test has two main parts. First, eight fixed exchange-traded fund sleeves were started with 1250 USD each, and cash was reinvested independently in each sleeve. The initial weights of the sleeves were equal, but they were allowed to drift over time without being rebalanced monthly. A new position was entered at the next session's open if the previous month's return was positive, with no short selling or leverage used. The parent trend was held until the last session of the month, with no stop or target, and was liquidated at the end of the month. Second, the test was trained on data from 2017 to 2020, with a holdout period from 2021 to 2025, and an extension from January to August 2026. A warm-up period was used in 2016, with no invented early history. Fees were 1 basis point plus 15 basis points for slippage on each side of a trade. The results of the test, which are simulated portfolio returns and not actual account returns, were as follows: in 2021, the return was -2.0080833581230917 percent, in 2022 it was -2.270405986327506 percent, in 2023 it was 0.41805183322796147 percent, in 2024 it was 2.3875767421257965 percent, and in 2025 it was 11.776261979038939 percent. The test used daily open, high, low, and close prices, and did not account for 15-minute venue exits, gap overshoot, or national best bid and offer prices. The test also used fractional sizing and did not include fixed business costs. The exchange-traded fund adjustment used in the test means that all returns are proxy data, and not excess returns from futures, inverse-volatility scale, or original long-short paper replication. The era used in the test was reused from prior research and is not untouched prospective evidence. The conclusion is that the parent trend is diagnostic only and cannot transfer its edge to different exits.

This is a test of a trading strategy called QTR9090200. The strategy has the following rules: it starts with eight fixed exchange-traded fund, or ETF, investments, each worth 1250 USD, and it reinvests any cash it receives. The strategy does not use leverage, or borrowing money to invest, and it does not sell stocks short, or bet that their prices will fall. It buys stocks when the previous month's return is positive and holds them until the end of the month. The strategy was tested using data from 2017 to 2026, with some years used for training and others used to see how the strategy would perform in real life. The strategy charges a fee of 1 basis point, or 0.01 percent, plus an additional 5 basis points for buying and selling stocks. The results of the test are as follows: in 2021, the strategy lost 0.51 percent; in 2022, it lost 1.25 percent; in 2023, it gained 1.61 percent; in 2024, it gained 4.48 percent; and in 2025, it gained 14.30 percent. These results are based on simulated trades, not actual investments, and they do not include any partial months. The data used for the test came from several sources, including a website and a research paper. The strategy is only for testing and cannot be used to make actual investment decisions.

This is a description of a trading strategy. The strategy has eight parts, called ETF sleeves, which start with $1250 each and reinvest any cash they make. They do not rebalance monthly, meaning their weights can change over time. The strategy buys when the previous month's return is positive and sells at the end of the month. It does not use leverage or short selling. A trading period, or trend, is considered long-only, meaning it only buys, not sells. The strategy was trained on data from 2017 to 2020, tested on data from 2021 to 2025, and further tested from January to August 2026. It includes fees of 1 basis point plus slippage of 5 basis points for each buy and sell. The results for each year are as follows: 2017 had a return of 6.355536569709552%, 2018 had a return of -5.562579921964328%, 2019 had a return of 6.404240580754461%, and 2020 had a return of 0.42316346016491035%. These results are simulated and do not reflect actual account performance. The data used is proxy data and does not include some costs. The strategy is for diagnostic purposes only and its success cannot be transferred to different trading exits.

A new review of the publicly available September slides for QTR9090200 INBX has filled a previous gap in safety data. This review is based on existing information and does not indicate a new publication since the September 8 release. The data shows higher rates of severe related events and discontinuations, which complicates the favorable response reported earlier. The proposed accelerated pathway is still just a proposal and not an agreement with the FDA. As a result, confidence in the initial positive headline should be downgraded, and no allocation to the clinical stock should be made. However, some argue that the benefits may outweigh the risks for patients, and further subgroup analysis may confirm efficacy. These findings do not prove a negative stock return but rather provide more complete safety information. The analysis is limited by the sponsor's reporting and the lack of independently reviewed results. The starting cash position is $245.69, with the goal of achieving a repeatable net equity edge, but this is constrained by the lack of a validated clinical event strategy. The information comes from the Inhibrx website, specifically the hexagon slides and investor pages.
The QTR9090000 decision is to keep $245.69 in cash, as the reversal adaptation did not meet the qualification requirements. The goal is to achieve a positive and repeatable net return, with a binding constraint of independent costed actual entry and exit edge. The premises for this decision are based on three points. Firstly, a new frozen weekly sector reversal managed holdout of 219 trades showed a return of 12.48156%, a drawdown of 19.17883%, a profit percentage of 55.25114%, a win rate of 1.58622%, and a loss rate of 1.79603%, with a mean return of 0.072705%. However, the 95% confidence interval includes 0 and the cost stress is -27.41278%. Secondly, the Nagel paper's original liquidity supplier long short conditional risk payoff differs from the cash ETF weekly rule, with 15-minute exits and whole-share partials unvalidated and fixed operating costs omitted. Thirdly, the INBX unchanged daily close and same clinical topline do not create an independent clinical stock payoff distribution, with a full bear fundamental recorded. The conclusion is that there is no approved notional, and no propose, exit, adjust, or fund actions are taken. The decision is valid under the qualification gate, with soundness conditional on test data, but it does not prove that all quant strategies fail. A counterargument is that a positive 2026 extension with 35 trades and a return of 10.78925% could support future work, but it does not supply an untouched costed edge or permit retrofitting. The nominal position cap is $212.7475, with a risk of 8.5099, and there are no held stops or targets. The rates are based on a 2.38% annual compound full research capital over five years, with no required $349 USD profit in 23 days. Research qualification would change only with pre-registered new independent costed data, actual 15-minute fill coverage, integer lot/profit protection rules, and a positive conservative edge. The scope has been broadened to 9 liquid sector ETFs, with a country collector retained and crypto/PEAD not forced into another untested bet. A news scan found the headline from https://inhibrx.investorroom.com/news-releases, and data lines were found from https://www.nber.org/system/files/working_papers/w17653/w17653.pdf and https://runway.adityaperswal.workers.dev/data/stock-bars.
The automated trading fund manager reviewed the price and indicators for QTR9090000. On September 1 at 00:02, a delayed request confirmed the INBX price on September 8 was 114.34, which is a -5.6367088% change from the price on September 4, which was 121.17. The high was 120.1825 and the low was 94.0001, with a close that was unchanged from 21 UTC, but the volume was 1674071, which is higher than the previous volume of 1616846, and the count was 29332, which is higher than the previous count of 29269. The SPY price was 765.96, which is a -0.5492151% change from the previous price of 770.19, with an unchanged close. The provider's daily aggregate is not verified and there are 61 missing regular minutes that remain separate from the prior vintage. The current-time end request was 403, while the 23:40 cutoff was 200, indicating a difference in recent entitlement from historical access. The 5-day descriptive returns for nine ETFs from September 8 adjusted close were: XLB -1.42342%, XLE 1.26642%, XLF -0.71045%, XLI -0.40541%, XLK 0.73458%, XLP -1.12968%, XLU 2.88894%, XLV -1.99953%, XLY -2.23004%, and SPY -0.14210%. XLY was the worst performer and does not allow for a Tuesday night catch-up to the weekly next open specification. All ETFs had a 20-session close volume proxy of 569.98m-1.6339bn USD/day, but the displayed liquidity was not of fill quality. Prices ranged from 43.45 to 187.87, suggesting that one whole ETF share can fit a 212.75 position cap, but this is not a qualified edge, and a partial half may leave a fractional residual with different after-hours execution. The prior 20 mean H-L stop-1R/target 1.5R plus profit protection has already been tested and failed robustness. The conclusion is that there is no need for live exits based on need, and there are no holdings to adjust. A counterexample of a favorable INBX rebound does not change the independent clinical edge sample 0. The facts and provider coordinates are separate from execution assumptions, with source observations 16020/16049-58 and prior 1246. An archival clarification notes that earlier 21 UTC raw values were retained in journal observation 15965, not claimed local raw response, and local files hold this run 403 and successful retry. The sources are https://runway.adityaperswal.workers.dev/data/stock-bars?feed=sip&adjustment=raw and https://runway.adityaperswal.workers.dev/data/stock-bars?feed=sip&adjustment=all.
The trading fund manager's notes are as follows: the ledger is open and no orders are being held, so there are no current investments or progress to report. The INBX watch has three consequence levels: first, a favorable response on September 8 can reprice equity; second, subgroup uncertainty and funding needs may alter the regulatory path; third, additional capital costs and trading costs can prevent stock profit. A strong bear market is not sufficient to derisk versus valuation, and a strong bull market is characterized by continued randomized benefit and cash-supported development. The source sponsor benefits from positive capital pricing, but syndication does not add independence. The TYRA and IRD watches also have three consequence levels: first, upcoming data may reprice; second, endpoint hierarchy and patient selection may qualify the headline; third, gaps and financing may dominate any drift. No outcome can be inferred before data is released, and existing monitors retain both branches. A reverse experiment shows that liquidity selling pushes losers lower, and inventory risk may pay a reversion premium, but cash ETF buyers paying the spread are not market makers. Facts include a cost stress of negative 27.41% for N219, but the mechanism is not causally identified. The cash thesis bear is that cash misses rallies and recurring costs deplete the runway, making the monthly profit threshold harder to achieve. The counterargument that profit requires deployment is only true given a positive edge, not an adequate premise for unknown payoffs. The goal is a positive profitable book from cash of 245.69, with a binding constraint of a qualified edge, not symbol availability. There are no need-driven stops or targets, and no FUND expansion is planned. Sources include press releases from Inhibrx, Tyra Bio, and Opus GT, as well as a working paper from the National Bureau of Economic Research and QTR9090000 backtests.
A news scan found the text of a block of notes from a fund manager. The notes start with the current equity at 850.99 and quant cash at 245.69, with the goal of achieving repeatable net profit while considering edge uncertainty. The manager makes two premises: first, using 219 completed fixed rule returns from 2021 to 2025 with a base of 6 basis points per side and stress of 16 basis points per side, and second, using a NumPy seed of 9090000, 20,000 paths, 100 sequential trades, and circular 5 trade blocks, with each trade hypothetically investing 25% of the evolving account equity. The base terminal percentiles are -5.54344%, +1.53083%, and +9.92274%, with a loss probability of 36.68%, a 10% drawdown probability of 0.85%, and a 95th percentile drawdown of 7.78848%. The stress percentiles are -10.13895%, -3.41932%, and +4.55102%, with a loss probability of 77.075%, a 10% drawdown probability of 11.14%, and a 95th percentile drawdown of 11.33923%. The conclusion is that the simulated upside is not robust to an extra 10 basis points of slippage on each side. The claim of 100 trades in 23 days is not valid, as the runway window differs from the 5-year horizon of approximately 219 trades. The sampling assumes that the past block distribution will repeat, but it does not model new crashes, 15-minute exit overshoot, whole lot rounding, fixed monthly costs, or censored missing fills. The scenario of 25% notional is not approved risk and does not guarantee a 1% loss limit. The binary payoff uses a normalized loss quarter Kelly formula, which is 0.01145882 for the base and floored at 0 for stress. This quantity is a fraction at risk in average-loss units, not automatically position notional. The full variable payoff Kelly with unbounded tail risk would need a separate model. The adopted size is 0 because the confidence interval includes 0 and the stress is negative. The hard position cap is 212.7475 and the nominal risk is 8.5099, which are caps, not sizing recommendations. A counterexample could be that the cost could actually remain at 6 basis points, but unknown execution cannot be assumed from daily liquidity, and the operator needs 349.01 changes with no probability. The source of the observation is 16076, with backtests QTR9090000, and the data can be found at https://runway.adityaperswal.workers.dev/data/stock-bars.
A news scan found the headline about QTR9090000 reversal uncertainty. The analysis is based on four premises. First, a managed fund with a 5-day holdout from 2021 to 2025 had 219 trades, with 121 of them being positive, a mean return of 0.0727050%, a win rate of 1.5862244%, and a loss rate of 1.7960281%. The total return was 12.48156%, with an annual compound rate of 2.38027%. Second, a statistical method called bootstrap, which is a way to estimate the uncertainty of a result, was used to analyze the data, giving a 95% confidence interval of -0.1643239% to 0.3210968% per trade. The positive fraction of 0.7152 is not a probability that the result is true. The correlation between trades, which is a measure of how much they move together, was -0.06355. Third, a regression analysis, which is a way to understand the relationship between two things, was done on the daily close equity returns compared to the SPY index, which is a stock market index, using a method called OLS with a correction for errors, and found a beta of 0.25433, an alpha of -0.0017566% per day, a t-value of -0.08235, and an R-squared of 0.12165. The gross return of the SPY index from January 4, 2021, to December 31, 2025, was 97.9859%. Fourth, when including costs, the mean return was -0.1272406%, and the return was -27.41278%, with all six stress variants losing, and only two of the six base variants being positive. The conclusion is that there is no statistically established tradable alpha, which means that the strategy does not beat the market. The inference is valid only for this simulation, and its soundness is limited by the assumptions made. A strong counterexample is the positive return of 10.78925% in 2026, but it does not erase the failed training result of -6.78617%. The prior skeptical view is not universally rejected, but any change should be based on fresh, independent results. The clinical side calculation, which is a way to analyze the results of a trial, found a p-value of 0.114704, but it was not a prespecified test and does not assert trial failure. The sources of the data are observations 16059-16076, https://runway.adityaperswal.workers.dev/data/stock-bars, https://www.nber.org/system/files/working_papers/w17653/w17653.pdf, and issuer observation 16026.
A preregistered note, number 1253, was written before data was retrieved. The test used nine sector ETFs, ranking them by their adjusted close returns over the prior 10 sessions at the weekly boundary. It bought the worst performer at the next open if its return was negative. Subtracting SPY, which is a type of stock market index fund, did not change the rankings. The test used a stop-loss, which is a rule to sell a security when it reaches a certain price, and a target price, which is a desired sale price. The stop-loss was set at 1 times the average high-low range, and the target price was set at 2 times the average high-low range. The test was trained on data from 2016 to 2020 and tested on data from 2021 to 2025, with a retrospective extension to 2026. Late trades that crossed the weekly boundary were omitted. The test used a full normalized capital of $10,000, with cash only, and fees of 1 basis point, which is a unit of measurement for interest rates, and slippage of 15 basis points. The results were verified by a vectorbt, which is a type of backtesting tool, and the final result was $6,092.56. The test used a stop priority on daily collisions, which is when two or more trades occur at the same time, and an adverse gap stop at the open, which is when the price gaps down at the open. The results showed a sample size of 222, with a p-value of 0.5495, a win rate of 28.85%, and a loss rate of 20.25%. The mean return was -0.20%. The test also showed yearly returns of -1.72% in 2021, -14.36% in 2022, -19.44% in 2023, -7.18% in 2024, and -3.19% in 2025. The exit counts were 112 for stop, 42 for time, 35 for breakeven, 26 for target, and 7 for target gap. The return and drawdown, which is the peak-to-trough decline in value, are based on full research capital and daily close marks, not account performance or worst intraday drawdown. No fixed monthly platform charges were deducted, which would have worsened the net economics. The sources used for this test include a working paper from the National Bureau of Economic Research and a stock bars feed from a website. The observations used were from 16049 to 16076, and the local research file was reversal.py.
A preregistered note, number 1253, was written before data was retrieved. The test involved nine sector ETFs, which were ranked based on their adjusted close returns over the prior 10 sessions at the weekly boundary. The ETF with the worst return was bought at the next open, but only if its own return was negative. The SPY subtraction, a way to compare the ETFs, did not change the cross-sectional ranks. The prior 20 session mean high-low range, a measure of price movement, was used to set the initial stop loss at 1R, the target at 2R, and the remaining stop entry at 1R, with a maximum next weekly open. The test was trained on data from 2016 to 2020, tested on data from 2021 to 2025, and retrospectively extended to 2026. Late boundary-crossing trades were omitted. The test used all 10 series, with 2685 aligned sessions from January 2016 to September 8, 2026, and no missing value fill, adjusted OHLC, and a survived ETF set. The test started with a full normalized capital of 10000, with cash only, and fees of 1bp and slippage of 5bp each side, including partials. A custom event cash and every equity point was verified by vectorbt from orders, with an exact final value of 9497.888005990975. The stop priority was set on daily collisions, with an adverse gap stop at open, target gap recognized, and partial/BE ambiguous days assigned adverse sequence. The test used continuous touch, which is optimistic versus 15-minute polling, even though the collision rule is conservative. The test did not exactly replicate the Nagel replication, which used 48 industry/individual stocks, long-short, 5 daily sleeves, conditional beta hedge, closing liquidity supplier, and VIX dependence. The ETF cash adaptation tests a different payoff. The premises of the test were: 1, recorded returns from a fixed rule; 2, base positive edge must survive costs and uncertainty; and 3, the whole family fails stress and CI. The conclusion is that this is research-only, with no allocation. The sample size was 222, with a p-value of 0.5495495495495496, a W of 1.4912659127355696%, an L of 1.8291627507384938%, and a mean of -0.004422674414909376%. The returns by year were: 2021, 6.896128739344354; 2022, -6.859962703773414; 2023, -11.855230711768904; 2024, 1.7638338800762154; and 2025, 6.350283913282184. The exit counts were: stop, 112; time, 42; breakeven, 35; target, 26; and target gap, 7. The trade sample counts were completed round trips, with partial legs aggregated. The return and drawdown are full research capital and daily close marks, not account performance or worst intraday DD. No fixed monthly platform charges were deducted, which would worsen the net economics. All historical windows were previously used by other fund studies, not pristine OOS, and no winner was chosen from a sweep.

The years 2021 to 2025 had returns of -6.5788%, -11.4885%, -16.6819%, -9.8307%, and 0.2925%, respectively. The exit counts were 104 for stop, 45 for target, 35 for breakeven, 29 for time, and 9 for target gap.

The initial stop loss was set at 1 times the prior 20 session mean high-low range, the target at 1.5 times this range, and half of the position was closed at 1 times this range with the remaining position stopped at the next weekly open. The test was trained on data from 2016 to 2020, tested on data from 2021 to 2025, and retrospectively extended to 2026. Late boundary-crossing trades were omitted. All 10 series had 2685 aligned sessions from January 2016 to September 8, 2026, with no missing values filled, adjusted open, high, low, and close prices, and the ETF set survived. The test started with a normalized capital of 10000, used cash only, and included fees of 1 basis point and slippage of 5 basis points on each side, including partials. A basis point is a unit of measurement for interest rates and fees. The test results were verified by vectorbt from orders, with an exact final value of 9712.657588258156. The test prioritized stops on daily collisions, used an adverse gap stop at open, and recognized target gaps. The test was not an exact replication of the Nagel study, which used 48 industry and individual stocks, a long-short strategy, 5 daily sleeves, a conditional beta hedge, and closing liquidity supplier, and was dependent on the VIX, a measure of stock market volatility.
