Verdict

no verdict yet

11 of the 60 sessions before the first reading. No verdict until then.

The hypothesis, as registered

Someone who knows something buys calls, and the price shows it before the stock does. Under put-call parity a call and a put at the same strike and expiry must carry the same implied volatility; when the call's is higher, calls are relatively expensive. Cremers and Weinbaum (2010) found that gap predicts positive returns over the following days. This asks whether it survives on one session, on our shortlist.

The rule

For each finalist, invert Black-Scholes on the mid-price of the at-the-money call and put at yesterday's close, nearest expiry at least seven days out, both legs quoted with open interest of fifty or more. Take the finalist with the largest positive call-minus-put implied volatility spread; ties go to the higher quantitative score. The models' verdicts are not read. Abstains when no finalist's calls are priced above its puts.

Session by session

Newest first. The numbers in the middle column are the ones the rule actually read that morning. Losing days stay.

Best session +6.31%, worst -8.41%. Over this few sessions the mean is mostly the sum of its two or three largest days, which is the whole reason the verdict is read only after 60, 120, 250, 500 sessions and frozen in between.
