Conclusion current XLK190.55 qualifies individually under250 but cannot coexist with EEM67.37 in240fund; XLE64.63 fits. No single-name valuation inference warranted by ETF momentum. Beneficiaries of split: small whole-share investors obtain smaller trading units; not extra wealth.

R91906 refreshed18 signal table; EEM/XLE pending slots
Premises: (1) issuer originalNov20 2025 confirms2:1 splits effectiveDec5 forXLK/XLY/XLE/XLU/XLB; aggregate marketvalue unchanged. https://investors.statestreet.com/investor-news-events/press-releases/news-details/2025/State-Street-Investment-Management-Announces-Share-Splits-for-Five-Select-Sector-SPDR-ETFs/default.aspx . (2) our mandate requires whole shares, account250namecap and240fundcap. (3) fresh vendorall/split responses omit adjustment forXLK/XLE/XLU but notXLY/XLB (29327). Economic sharecount normalization repairs false -50%loss; it is not discretion to suppress genuine crashes. A2:1 split halves minimum purchasable economic exposure, making a constrained small whole-share account more granular, while creating no issuer cashflows or return by itself. CurrentXLK190.55limit individuallyfits250 but EEM67.37+XLK190.55=257.92 exceeds240. EEM+XLE64.63=132 fits, so XLE remains selected. Counterargument: issuer split event alone cannot establish which vendor series is defective; observed before/afterprice discontinuity plus officialratio identifies repair candidates, and already-normalizedXLY/XLB are explicitly spared. Underlying valuation/earnings are not recomputed because split does not change them; priorissuer exposure3393 is background, notnewdatedfundamentalclaim. No newfund or corporate-action-arbitrage edge inferred.

Premises: for each day compute lagged20 arithmeticATR divided by priorclose, then test nextopen/priorclose-1 < -2ATR/priorclose. This hypothetical threshold resets every day at priorclose; it is NOT entry-based live-stop backtest, excludes intraday and extended-hours exits and is not conditioned on momentum holdings.

R91904 overnight diversification fails the long-sample stability test
Premises: (1) previous daily close to next daily open is a gap proxy, not intranight path/fill; Alpaca conditionT excluded from daily OHLC https://docs.alpaca.markets/us/docs/market-data-faq . (2) repaired missingXLE2:1 split using issuer29327. (3) compare split-only price gaps with all-adjusted economic-return gaps. Primary bars https://runway.adityaperswal.workers.dev/data/stock-bars?symbols=EEM,XLE&timeframe=1Day&start=2019-01-01&end=2026-09-18T23:59:00Z&feed=sip append adjustment=split/all. MeasuredSep19.

XLE negative in EEM bottom5% gaps:66/97=68.04% full,35/63=55.56% fiveyear,2/13=15.38% recent; small conditional samples. Worst joint same-date gap scaled to static67.37/64.63 exposure16.23047 on2020-03-16; fiveyear4.98122 on2025-04-07; recent3.65555 on2026-06-23. These are scenarios not realized portfolio PnL. Full adjusted economic-gap correlation+.46190 and worst16.20275 corroborate qualitative result; dividend adjustment changes level slightly. Prior expected unstable diversification; evidence supports it without implying next-event probability. Fullsample marginal minima EEM-11.45545%2020-03-16,XLE-17.48235%2020-03-09 are DIFFERENT dates and must not be summed as observed joint loss. All measured outputs29349–58. Counterargument: 2020 regime may not recur; recent negative dependence may persist. Neither establishes a hard future bound. Soundness limited by daily proxy, vendor revision and selected universe; valid conclusion is no diversification-based size increase, not withdrawal from fixed momentum.
