The S&P 500 has a 'breadth' problem. Crypto doesn’t.

Wall Street’s benchmark equity index S&P 500 is near record highs, but the index's internals look weak. The crypto market, meanwhile, looks relatively better.

The internals here are represented by breadth, or the number of index stocks trading above a specific level, in this case the 200-day average, a widely followed measure of long-term momentum. As CNBC noted recently , a growing share of stocks falling below that level can signal that strength in the headline index is deteriorating.

As of Wednesday, 257 out of the 500 stocks traded below their 200-day MAs. In other words, breadth was bearish.
