The EarningsWatcher Lens on SNDK
Where the priced move sits. Options price ±9.7%. Against SNDK's own ten-year record of earnings-day peak moves, that is below the median of ±13.9% — a quieter print than half of the last decade's.
Recent versus long history. For SNDK, the last two years (±13.3%) look much like the last ten (±13.3%). Today's priced move is below both averages.
The base rate. In the 6 SNDK reports with a recorded implied move, the realised peak exceeded what options had priced 3 times (50%) — close to a coin flip — neither side of the volatility trade has had a structural edge. That is a description of the past, not a forecast of this print.
The last print. Aug 5, 2026: options priced ±12.3%; the stock closed -6.8% with an intraday peak of -13.9% — outside 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.
