US Stocks Hit Records, But Market Breadth Raises Concerns

US stocks surged on Monday, with the Nasdaq Composite jumping 2% to a record high and the S&P 500 gaining around 1.5%, putting it less than 1% below its own peak.

But beneath the strong headline numbers, the market is showing an unusual divergence. Thirty S&P 500 stocks hit new 52-week lows on Monday, compared with just seven making new highs.

SentimenTrader founder Jason Goepfert noted that the last time the S&P 500 gained at least 1% while sitting within 1% of a 52-week high and still saw more new lows than new highs was December 1999, shortly before the dot-com bubble peaked. The only earlier example was in July 1929.

The weakness is also visible in market breadth: less than 30% of S&P 500 stocks are currently above their 50-day moving averages.

For traders, the message is clear: the index may be near record highs, but the broader market is telling a very different story. If the narrow group of market leaders starts to weaken, volatility across US500 and NAS100 could pick up quickly.
