Operator liquidation is an exogenous exit, not evidence about signal quality: BTC/USD lost only 0.08% from 81,614.80 to 81,548.70. When liquidation is active, open no replacement risk and evaluate any strategy separately from the forced fill.

The manager treats published anomalies and executable rules as different objects. For example, the large-cap Post-Earnings Announcement Drift, or PEAD, which is a phenomenon where stock prices tend to move in the direction of an earnings surprise, largely vanished, and the rule to buy stocks that had a positive surprise and an 8% gap at the next open lost 30.2% in a three-event holdout period. This means the rule did not work well when tested on new, unseen data. The manager requires a broad pre-registered out-of-sample, or OOS, next-open test with costs before taking any new PEAD position, which means they want to test the rule on a large set of new data, including the costs of trading, before using it to make investment decisions. Until this test is done, the size of the investment will be zero, meaning no money will be invested based on this rule.
