Individual S&P 500 Stocks Are Not Rising With The Index

When I discuss the market’s breadth one of my go-to measures is the Advance-Decline Line. This tool simply looks at the number of stocks that are rising and falling and ideally we have more stocks that are going up than going down. So far, the A-D Line has continued to confirm the rise in stocks. Simple as that. But there is another tool that I like to watch and that breaks down the 500 stocks that make up the S&P 500 and examines where they are relative to their individual 52-week highs and lows. I looked at this indicator back in October of last in a post titled, We Haven’t Seen A Market Top Yet. And based on it’s current level while the S&P 500 is at (near) a new high, I began to dive deeper into the data.

We do not only want more stocks going up than going down when the U.S. market itself is rising but we want broad participation at new highs. Barry Ritholtz once shared some of the key signs Lowery’s Research looks for in a market top (note: I’m not calling for a market top in this post) in an article for Bloomberg. One of which is the number of stocks that are 20% or more below their 52-week high. Quoting Paul Desmond, chief strategist of Lowry’s:

When a major index such as the S&P 500 is making new highs but the number of SPX stocks making 52-week peaks begins declining, that divergence is a significant warning sign. Desmond notes that this can warn of an eventual top as much as a year ahead of time.

This point is what I’d like to take a look at today. One of the charts I review daily is below and shows the S&P 500 and an indicator that measures the average position of the individual S&P 500 stocks in relation to their own 52-week high and low on a scale of 100-0 with 100 being all of the stocks are at their 52-week high and 0 if all the stocks were at a 52-week low As of May 26th, we are at 63, meaning we are closer to stocks being at their mid-point (a reading of 50) between their high and low than they to mirroring the index and being near at fresh all-time high. So what’s this mean? Next I’ll review past examples of this taking place.
