Options Intent Radar
Earnings/event positioning
Options activity is concentrated around a live event window, so the cleanest read is event positioning rather than pure direction.
Options are pricing movement more than direction; compare expected move with the stock's actual weekly change.
Earnings/event positioning matters because it connects the options headline to the actual evidence: $9.5M of estimated gross traded notional, puts · 46-90 days · itm, and a volatility flow versus price backdrop. Use it as a research priority signal, then validate the chart, liquidity, event calendar, and risk before acting.
