PCR Explained: Put-Call Ratio for Option Trading Sentiment
Understand put-call ratio (PCR), how to read it on Nifty and Bank Nifty, and why PCR analysis matters for intraday bias.
What Is Put-Call Ratio (PCR)?
Put-Call Ratio (PCR) compares put open interest to call open interest. A PCR above 1 means more put OI than call OI; below 1 means the opposite. Traders use PCR as a contrarian or confirming sentiment indicator depending on context and methodology.
PCR is typically calculated on index options using total put OI divided by total call OI for a chosen expiry or across expiries. It is one number summarising a complex option chain — useful, but never sufficient alone.
How Traders Interpret PCR
Elevated PCR is often read as bearish positioning or hedging — puts dominate. Extremely high PCR sometimes precedes reversals (contrarian view: everyone is already hedged). Low PCR suggests bullish positioning or call writing — complacency risk before corrections.
Bank Nifty PCR can swing faster than Nifty due to higher volatility and aggressive weekly participation. Intraday PCR change matters as much as the absolute level — a rising PCR into a falling market confirms put buying; a falling PCR into a rally may show call chasing.
- PCR > 1.2: elevated put interest — caution or hedge-heavy book
- PCR 0.7–1.0: balanced to mildly bullish positioning
- PCR < 0.7: call-heavy — watch for reversal if price stalls
- Intraday delta: compare PCR open vs current for session shift
PCR Pitfalls
PCR ignores strike distribution. Heavy put OI far below spot hedges portfolios without implying a crash prediction. Call writing at OTM strikes inflates call OI without bullish intent. Always inspect the chain, not just the ratio.
Event days distort PCR. Before budget or election results, put buying for protection spikes PCR artificially. After the event, IV crush can collapse put premiums while OI adjusts — read our PCR analysis research for structured approaches.
PCR in Your Daily Routine
Morning checklist: note PCR vs 5-day average, identify whether change is driven by puts or calls, cross-check with highest OI strikes and spot location. If PCR rises while price holds support, bears may be overpaying for protection — bullish undertone possible.
Combine PCR with max pain and OI trend charts for expiry-week framing. Single-indicator trading is a common path to losses.
Frequently Asked Questions
- Is high PCR bullish or bearish?
- High PCR means more put OI — often interpreted as bearish positioning or hedging. Contrarian traders sometimes view extreme PCR as a bottoming signal. Context decides.
- Should I use volume PCR or OI PCR?
- OI PCR is standard for positional sentiment. Volume PCR reflects today's trading activity — useful intraday but noisier.
- Does PCR work on expiry day?
- Expiry day PCR is distorted by rolling and gamma effects. Use it with caution; prefer strike-level OI and max pain.
Key Takeaways
- PCR = put OI divided by call OI — a sentiment summary.
- Extreme readings can be contrarian or confirming depending on setup.
- Always validate PCR with strike-level OI on the option chain.
- Track PCR change intraday, not just the opening snapshot.
