The $S&P 500(.SPX)$ is just 0.7% below its all-time high. But underneath the index, the picture looks very different. 📉 The median $SPX stock is 16% below its 52-week high. Only 51% of $SPX stocks are above their 200-day moving averages. Yet the index is still within roughly 0.5% of a record. That combination is extremely unusual. The last time the market saw a similar setup was March 2000, when the index was near record highs while participation underneath was already deteriorating. 👇 The key takeaway: Index strength ≠ broad market strength. A handful of large stocks can keep the $SPX near its highs even while a much larger part of the market is already correcting. That makes market breadth one of the most important things to watch right now.
