The S&P 500 has been going up for 9 days in a row, but here's the problem: fewer and fewer individual stocks are actually joining the rally. Almost all the gains are coming from a handful of giant companies, which is a classic warning sign that the market is more fragile than it looks.

## Idea

When a stock market index keeps hitting new highs but only a few big names are carrying the load, history shows it often ends with a pullback. Right now, the S&P 500's 9-day win streak masks the fact that most stocks aren't actually going up. That means if even one or two of those giant leaders stumble, the whole index could drop fast. One smart response is to rotate into defensive sectors like utilities or consumer staples — these tend to hold up well when the broad market finally corrects. Think of it as buying insurance while the party is still going.
