The options market is where informed traders place their bets. Because options provide leverage and defined risk, institutional participants use them to express directional views — often before those views are visible in stock prices.

Why Options Flow Leads Price

Pan & Poteshman (2006) published a landmark study in the Review of Financial Studies demonstrating that options volume contains predictive information for future stock returns. Their finding: stocks with high call-to-put ratios outperformed those with low ratios by a meaningful margin.

The mechanism is straightforward. When an institutional trader has conviction about a stock's direction, options offer the best risk/reward for expressing that view. A $10 million directional bet through stock is visible and moves the market. The same bet through options can be placed with less capital and less market impact — but it still shows up in the flow data for those who know where to look.

What We Track

Alpha Pulsx analyzes several dimensions of options market activity:

  • Call/Put Volume Imbalance — When call volume dramatically exceeds put volume (or vice versa), it signals directional conviction. But context matters: a call imbalance during a selloff means something different than the same imbalance during a rally.
  • Unusual Activity Flags — When options volume in a specific strike or expiry spikes far above normal levels, it often signals informed positioning. We flag these for the confluence model.
  • Open Interest Changes — New positions being opened (rising OI with volume) versus existing positions being closed tells a different story. We distinguish between the two.
  • IV Skew — When put implied volatility is significantly higher than call IV, the market is pricing in more downside risk. Changes in skew often precede directional moves.

The Noise Problem

Not all options activity is directional. Market makers hedge. Institutions roll positions. Retail traders buy lottery tickets. The challenge is separating informed flow from noise.

Our approach focuses on patterns that have demonstrated predictive value: unusual volume relative to open interest, activity concentrated in specific expirations, and flow that conflicts with recent price action (contrarian positioning by informed players).

The Alpha Pulsx edge: We don't just count calls and puts. Our flow scoring evaluates the quality and context of options activity — distinguishing informed positioning from noise, and feeding a nuanced flow score into the six-pillar model.
