Market Rebalance Targets Concentration Risk in Leading Indexes

The imminent rebalance of the S&P 500 and Nasdaq-100 indexes signals a move to address the ongoing concern of concentration risk in these leading market measures. This issue stems from the outsized influence of a handful of technology behemoths. Notably, five pivotal companies - Apple, Microsoft MSFT, Amazon, Nvidia NVDA, and Alphabet - collectively command approximately 25% of the S&P 500's weight. The situation is even more pronounced in the Nasdaq-100, where these five, along with an additional company, account for about 40% of the index's valuation. As these technology giants have expanded their market capitalizations, their sway over index movements has intensified, raising caution among investors and index committees alike.
