What Is a Market Indicator?
Like a technical indicator, a market indicator is a series of data points derived from a formula. In this case, however, the formula for market indicators is applied to the price data for multiple securities within the market, instead of just one security. Price data can come from open, high, low or close points for the securities, their volume, or both. This data is entered into the indicator formula and the data point is produced.
Unlike technical indicators, market indicators are not charted above or below the chart. Market indicators are what is being charted, and as such have their own ticker symbols. There are often many symbols that apply the market indicator formula simply to different markets. For example, the $BPSPX and $BPNDX track the Bullish Percent Index for the S&P 500 and the NASDAQ 100 respectively.
Bullish Percent Index (BPI)
The Bullish Percent Index (BPI) is a popular market breadth indicator that is calculated by dividing the number of stocks in a given group (an exchange, an industry, etc.) that are currently trading with Point and Figure buy signals, by the total number of stocks in that group. Bullish Percent levels that are above 70% are considered overbought, whereas levels below 30% are considered oversold. Strong buy signals occur when the Bullish Percent Index falls below 30% and then reverses up by at least 6%. Conversely, promising sell signals occur when it goes above 70%, and then reverses down by at least 6%.
It is important to note that the Bullish Percent Index is not something that can be applied to a single stock but rather an index that is calculated for a group of stocks.
The most popular version of this chart is the NYSE Bullish Percent ($BPNYA) which is mentioned prominently in Thomas Dorsey's book, Point & Figure Charting, however it is important to remember that the Bullish Percent index can be calculated for any grouping of stocks.
Because the NYSE's Bullish Percent Index is so closely followed, each day we also publish the list of NYSE stocks with P&F buy signals as well as the list of all stocks in the current NYSE "universe". Those lists can be found on our NYSE BPI Components page.
Traditionally, the Bullish Percent indicator is charted on a Point and Figure chart (example) using a 2 point box size. However, the indicator can also be charted and studied using standard charts (example) as well.
