Certainly! The Put-Call Ratio (PCR) is a statistical indicator used in options trading to gauge market sentiment. It compares the trading volume of put options (which give the right to sell an asset at a predetermined price) to that of call options (which give the right to buy an asset at a predetermined price) for a specific underlying security (such as a stock or ETF) within a given timeframe (usually a day or a week). The formula for calculating the PCR is:
PCR=Call Option OI / Put Option OI
Here’s what it tells us:
A rising PCR (greater than 0.7 or exceeding 1) indicates that traders are buying more puts than calls. This suggests bearish sentiment, as investors may be speculating that the market will move lower or hedging their portfolios against a potential sell-off.
A falling PCR (below 0.7 and approaching 0.5) is considered a bullish indicator. It means more calls are being bought relative to puts, signaling optimism about a bull market ahead.
Remember that the put-call ratio can be influenced by recent events, earnings reports, and overall market conditions.
