Introduction to Bullish Percent Index (BPI)
The Bullish Percent Index (BPI) is a technical indicator used to measure market sentiment and determine overbought or oversold conditions. It helps traders analyze market breadth by calculating the percentage of stocks currently showing a Point & Figure (P&F) buy signal within an index.
What is Bullish Percent Index (BPI)?
The BPI is a market breadth indicator that ranges from 0 to 100% and is designed to highlight bullish or bearish conditions. It operates on the concept of market participation, indicating whether a broad set of stocks is in an uptrend or downtrend.
Calculation of Bullish Percent Index (BPI)
The BPI is calculated using the following formula:
BPI = (Number of stocks on P&F Buy Signal / Total Number of Stocks in the Index) × 100
Example Calculation:
Assume there are 500 stocks in an index.
Out of these, 300 stocks are currently giving a P&F buy signal.
BPI = (300/500) × 100 = 60%
A reading above 70% indicates overbought conditions, while below 30% signals oversold conditions.
Key Strategies Using Bullish Percent Index (BPI)
1. Overbought and Oversold Signals
Above 70% → Market is overbought, potential reversal or correction.
Below 30% → Market is oversold, potential buying opportunity.
2. Trend Confirmation
If BPI is rising, more stocks are giving buy signals → Bullish trend.
If BPI is falling, more stocks are giving sell signals → Bearish trend.
3. Divergence Strategy
If the market is making new highs but BPI is not increasing, it signals weakness.
If the market is making new lows but BPI is rising, it indicates potential strength.
4. Crossing 50% Mark
Above 50% → More stocks are in a buy mode, indicating bullish sentiment.
Below 50% → More stocks are in sell mode, indicating bearish sentiment.
