Median gain from the close of the session the event was known, over each holding period; Reaction day (earnings only): the session that first traded on the report, from the close before it; under it, how many of the past events were followed by a gain (12/20 up). "Big" is SOXX's own: its worst / best 10% of days over the prior 2 years. Highlighted: happening in the latest session or today, from the live quote.
Big drop (-3.1% or worse)
A daily fall among the stock's own worst 10% of the prior 2 years.

The same event split by where SOXX 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: each cell shows how many past events it rests on.

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. This is history, not a forecast: in our backtests, how a stock did after its past events did not predict its next one. Not advice.
