What is the Bullish Percent Index (BPI)?
The Bullish Percent Index (BPI) is a breadth indicator used to assess the percentage of stocks within a specific index or sector that are in a bullish trend. It provides insights into the market’s overall momentum and helps traders identify potential trend reversals and the strength of market movements.
BPI is typically calculated based on point-and-figure charts, which are used to plot price movements and filter out the noise of price fluctuations. A high BPI value indicates that a large percentage of stocks are in a bullish trend, while a low BPI value suggests a bearish or weakening trend.
How to Calculate the BPI Indicator?
The calculation of the BPI involves the following steps:
- Select the Index: Choose the index or sector you want to analyze.
- Determine the Bullish Signals: Count the number of stocks within the index that are currently showing bullish signals on their point-and-figure charts.
- Calculate the Percentage: Use the formula:
BPI = (Number of Bullish Stocks / Total Number of Stocks) × 100
| Index | Total Stocks | Bullish Stocks | BPI |
|---|---|---|---|
| Index A | 100 | 60 | 60% |
| Index B | 150 | 90 | 60% |
| Index C | 200 | 40 | 20% |
Applications of the BPI Indicator in Trading
The BPI Indicator is widely used for:
- Identifying Market Trends: A high BPI indicates a strong bullish trend, while a low BPI suggests a bearish trend.
- Spotting Trend Reversals: Traders look for significant changes in the BPI to identify potential trend reversals.
- Confirming Other Signals: The BPI can be used in conjunction with other indicators to validate trading signals.

BPI vs. Other Market Indicators
While the BPI is a valuable indicator, it is important to compare it with other market indicators:
- Relative Strength Index (RSI): Unlike the BPI, which focuses on the percentage of bullish stocks, RSI measures the speed and change of price movements.
- Moving Averages: Moving Averages smooth out price data to identify trends, while the BPI provides a broader view of market breadth.

Common BPI Trading Strategies
Some common strategies using the BPI Indicator include:
- Bullish Signal Strategy: Buy when the BPI is above a certain threshold, indicating a strong bullish market.
- Bearish Signal Strategy: Sell or short when the BPI falls below a specified level, indicating a bearish trend.
- Divergence Analysis: Look for divergences between the BPI and market price to spot potential reversals.
Example: If the BPI falls below 30% while the market is showing bullish signals, it might indicate a potential buying opportunity as the market could be oversold.
Limitations of the BPI Indicator
Despite its usefulness, the BPI Indicator has some limitations:
- Lagging Indicator: The BPI may not provide timely signals as it is based on historical data.
- False Signals: The BPI can sometimes generate false signals, especially during volatile market conditions.
Conclusion
The Bullish Percent Index (BPI) Indicator is a valuable tool for assessing market trends and identifying potential trading opportunities. By understanding its calculation, applications, and limitations, traders can effectively incorporate the BPI into their trading strategies.
