Earnings beat + price still rising afterward + sector also supportive + options flow bullish. Classic PEAD.
The company beat earnings expectations, the market responded with a sustained (not one-day) positive price reaction, the sector isn't dragging the ticker, and derivatives markets are also positioning bullishly. All four data sources confirm the same story.
Bernard-Thomas 1989 post-earnings drift is one of the most replicable anomalies in finance — the top decile of earnings surprises earns ~8% excess return over the following 60 days. Pan-Poteshman 2006 options flow adds a cross-asset confirmation signal.
The drift weakens for companies that beat but guide lower for the next quarter. Also, accelerated drift reversal happens if short interest builds rapidly post-beat (indicates smart money betting against the move).
