Why Per-Strike PCR Is More Useful Than Aggregate PCR
PCR by Strike is a sentiment X-ray. The aggregate PCR gives you a blurry picture, this gives you the scan, strike by strike.
The headline Put-Call Ratio averages sentiment across the entire options chain, which can be misleading. A stock can show a neutral aggregate PCR while having extreme bearish positioning concentrated at one strike and extreme bullish positioning at another. PCR by strike cuts through this — it shows you exactly where the directional conviction is, not just how much exists in total.
This granularity matters because the positioning at specific strikes has specific consequences. A strike with PCR of 3.0 sitting 5% below the current price means institutional players have loaded up on put protection at that level — creating a defined support zone where dealer hedging will buy the dip if price reaches it.
Extreme PCR readings are sometimes contrarian signals. A PCR above 2.0 near current price can indicate that fear has peaked and the market is overhedged — historically, these extremes have marked short-term bottoms as put buying exhausts itself. Always read PCR in the context of trend, not in isolation.
The Difference Between Hedging and Speculation
High put OI at strikes far below current price is almost always protective hedging — portfolio managers buying insurance. High put OI at strikes near current price, especially if it appeared suddenly, is more likely directional speculation. The distinction matters: hedging creates support, speculation creates pressure. Watch where the PCR is elevated relative to spot to understand the intent.
PCR and Upcoming Expiries
PCR by strike is most actionable when filtered by a specific expiry rather than aggregated across all dates. The positioning that matters most is in the nearest active expiry — those are the contracts that will drive dealer hedging flows over the next few days. Longer-dated PCR reflects macro positioning that is less likely to create near-term price impact.
