Investors who have enjoyed a relentless climb in stock prices may want to keep a closer eye on the fine print. While major indexes like the S&P 500 continue to hover near all-time highs, analysts at Ned Davis Research are sounding an alarm over a rare and troubling disconnect known as market breadth. Essentially, while the big numbers look great, far fewer individual companies are actually participating in the rally, suggesting that the current bull market could be entering its final stretch.
According to data from NDR, the internal health of the market is deteriorating rapidly. In recent weeks, fewer than 25 percent of stocks in the S&P 500 have traded above their 50 day moving averages, and less than half remain above their 200 day marks. This creates a stark contrast where a handful of massive mega cap stocks are propping up the entire index, effectively masking deeper troubles beneath the surface. Strategists describe this as some of the worst breadth ever recorded while an index remains so close to its peak.
This specific type of divergence is historically ominous. Since 1980, these exact conditions have occurred only six times, often serving as a precursor to significant market tops, including downturns seen in late 2014 and 2021. When price action stays high but participation drops off, it typically introduces a downward bias for several weeks and often leads to a total market peak within about five months.
While some experts are still giving bulls the benefit of the doubt for now, others agree that there is severe damage under the hood. Analysts at HSBC noted that spiking bond yields have contributed to this decline in breadth. For many investors, the prudent move may soon be reducing equity exposure if upcoming year end rallies fail to bring more stocks back into the fold and prove that this growth is sustainable across the board rather than just limited to a few giants.
