The EarningsWatcher Lens on SAN
Where the priced move sits. Options price ±9.9%. Against SAN's own ten-year record of earnings-day peak moves, that is beyond the 95th percentile of ±7.8% — a size SAN has exceeded in about one report in twenty.
Recent versus long history. For SAN, the recent regime is louder than the long one: ±4.8% over the last two years against ±4% over ten. Today's priced move is above both averages.
The base rate. In the 10 SAN reports with a recorded implied move, the realised peak exceeded what options had priced 2 times (20%) — history here has favoured the sellers of movement. That is a description of the past, not a forecast of this print.
The last print. Apr 29, 2026: options priced ±7.0%; the stock closed -0.7% with an intraday peak of +1.6% — inside the priced range.
What this does not say. None of the above carries a direction. The implied move is the size of the move options are pricing, in either direction, and the history is how big past moves were — not which way the next one goes.
