How the Sentiment Algorithm Works This table evaluates market sentiment based on aggregated options data by expiration date. The key metrics are: Put/Call Ratio (PCR): Indicates the relative activity between put and call options. A high PCR suggests bearish sentiment, while a low PCR indicates bullish sentiment. Open Interest (OI): Represents the number of outstanding contracts. Higher values reflect strong market attention or hedging activity. Unusual activity ⚠️: Days with extremely high PCR or OI are flagged, signaling possible speculative bets or hedging pressures. The sentiment score is computed by combining PCR and OI, then classified into clear labels such as Strong Bullish, Moderate Bullish, Neutral, Moderate Bearish, Strong Bearish. Scores range from 0 to 100, where higher values indicate stronger bullish sentiment and lower values indicate stronger bearish sentiment.
