The Bull–Bear Index (BBI) measures whether traders allocate more capital to call options (bullish) or put options (bearish). It is calculated as the difference between call and put premiums from buyers, normalized by their sum. A value of 1 indicates only call option buyers (strongly bullish sentiment). A value of minus 1 only put option buyers (strongly bearish sentiment). Values near the middle represent a neutral balance. The index is also segmented by options maturity: Short term (Between 0 and 30 days): near term conviction. Mid term (30 to 90 days): tactical positioning and event driven bets. Long-term (>90 days): strategic positioning and structural sentiment.

This is the Point-in-Time (PiT) variant of Options Bull Bear Index (BBI). PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
