The poor breadth in the stock market is starting to worry investors. The S & P 500 rose to all-time highs on Monday, climbing above 7,400 as artificial intelligence continued to push the broader index farther above its March low; stocks are up more than 17% since falling to 6,316.91 on March 30. Memory stocks, especially, have been on a tear, with shares of Micron Technology more than doubling, up roughly 140%, over the same span. Take a look at the action beneath the surface, however, and the lack of participation outside of technology is concerning technical analysts. Friday, for example, was the first time over the last 30 years that the S & P 500 closed more than 7% above its 50-day moving average and not even 55% of its components were above their 50-day average, according to BTIG. The 50-DMA tracks near-term trends in a stock price. Usually, the percentage of companies in the S & P 500 that are above their 50-DMAs when the index is more than 7% above its own 50-DMA, has been 86%, on average, BTIG said. On Friday, the S & P 500 was higher by 7.7% on a headline basis, but just 52% of its members topped the same measure. More lows than highs Even more worrying, Friday was only the third time since 1990 that the S & P 500 made a new high when there were more new lows than highs, BTIG found. The two other times both came in December 1999, three months before the dot-com bubble peaked the following March. "Even if the tech/AI price action is justified, there is a difference between tech leading when most stocks are going up, and semis going parabolic when most non-tech stocks are moving sideways or lower," Jonathan Krinsky, chief market technician at BTIG, wrote on Sunday. "Perhaps the market is simply taking its time before we see the long-awaited broadening, but if we keep seeing 52-week lows expand, it's more likely we see tech 'catch-down' as opposed to the average stock 'catch-up,'" Krinsky added. Krinsky isn't the only one noting the market erosion. Jason Goep...
