Nearly half the stocks in the S&P 500 are at cross purposes with the rest of the market
Almost half of the stocks in the S&P 500 have a negative beta, evidence of a chasm between the entire index and its individual components.
TL;DR
- Approximately 45% of S&P 500 stocks have a negative three-month beta.
- A negative beta indicates a stock's returns moved opposite to the S&P 500 over a measured period.
- This divergence is linked to market concentration, with mega-cap tech stocks heavily influencing the index.
- Unusual market signals, like new lows outnumbering new highs on a day of index gains, have been observed.
- Sectors like energy, utilities, and consumer staples are noted for having negative beta stocks.
- The concentration in AI-related companies is a key driver, with beneficiaries performing strongly while others struggle.
- Experts suggest market leadership broadening could reduce negative-beta stocks, but dispersion is expected to remain elevated.
