20 #stocks make up 41% of the #S&P500 $SPY $QQQ #trading #markets

Largest 20 S&P 500 stocks up to 41% of the index's market cap. The most since 2000, according to NDR Research. This means there are greater chances that if a few of these stocks disappoint or outperform, the market could see strong swings in either direction. This is also a warning sign as the index gets more concentrated. Yet the capital-weighted index has largely outperformed the equal-weight as Big Tech stocks surged since the start of the year.
