How the Options Sentiment Score Is Calculated This sentiment framework evaluates market bias for GSK based on aggregated options data by expiration date. The key metrics are: Put/Call Ratio (PCR): Compares put and call activity. A higher PCR usually indicates more defensive or bearish positioning, while a lower PCR suggests bullish call demand. Open Interest (OI): Represents the number of outstanding option contracts. Higher open interest reflects strong market attention, hedging activity or speculative positioning around GSK. Unusual activity ⚠️: Expirations with extreme PCR or unusually high OI are flagged with a warning icon, signaling concentrated bets, hedging pressure or potential event-driven risk. The sentiment score combines PCR and OI into a 0–100 scale, then classifies each expiration into intuitive labels such as Strong Bullish, Moderate Bullish, Neutral, Moderate Bearish, Strong Bearish. Higher scores reflect more aggressive bullish positioning in GSK options, while lower scores highlight more defensive or bearish structures.
