Each row is one stock's latest event, with what that stock did the next month after its own past events of this kind (the past 5 years, from the close of the session each was known). We don't rank stocks on these records: in our backtests, how a stock did after its past events did not predict its next one, and across the S&P 500 no kind of event leaned up or down after its day. History, not a forecast. Not advice.
