Recent analysis reveals that nearly 45% of S&P 500 stocks have a negative three-month beta, meaning they are moving in the opposite direction of the index. This unusual trend is highlighted by Goldman Sachs and corroborated by CNBC, which noted that 40% of these stocks are negatively correlated with the index.
The S&P 500 recently rose by 1.5%, yet 30 stocks hit 52-week lows while only 7 reached new highs, a scenario reminiscent of the late 1990s dot-com boom. This divergence is largely attributed to the concentration of performance among a few mega-cap technology companies, which dominate the index's movements.
Adam Turnquist from LPL Financial explained that the performance of a small number of stocks can significantly influence the index, even when many others are underperforming. The low correlation among S&P 500 stocks means that large individual stock movements can offset each other at the index level.
Additionally, sectors like energy are contributing to the negative beta phenomenon, with Evercore ISI identifying 115 S&P 500 stocks with negative beta, particularly in energy, utilities, and consumer staples.
Analysts suggest that if market leadership broadens, the number of negative-beta stocks may decrease, but current conditions indicate a selective investment environment focused on AI beneficiaries.
The extreme readings of negative beta stocks may eventually revert to historical norms, but the current market dynamics differ from those of the dot-com era, as today's leading tech companies are more established with solid revenue streams
