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 lows but BPI is rising, it indicates potential strength.

4. Crossing 50% Mark
