Median gain from the close of the session the event was known, over each holding period; #rank among the S&P 500 stocks after the same kind of event (#1 = best). "Big" is CSGP's own: its worst / best 10% of days over the prior 2 years. Highlighted: happening in the latest session.

Crossed below 200-day avg

The close moves below its 200-day moving average.

Range of outcomes: all of CSGP's crosses below the 200-day average in the past 5 years, from the worst to the best result over each holding period; the box holds the middle half, the tick is the median. A wide box means the median alone says little. Hover the median for the average.

The same event split by where CSGP stood against its 200-, 50- and 20-day averages when it happened (a dip in an uptrend vs a falling knife); "vs" is the plain any-day median in that trend; "now" marks where it stands today. Splitting halves the evidence, so watch the confidence letters: H / M / L.

Aftermath: entry is the close of the first session the event was fully known (the same session for price moves, the reaction session for earnings, the next session for Reddit, analyst and insider events, which are dated by day). Repeats within a few sessions count as one event. Past performance after an event says nothing certain about the next one. Not advice.
