Green takes the top spot. And we’re not just talking about the Boston Celtics. Yesterday, Nvidia surpassed Microsoft to become the world’s most valuable company — pushing Apple down to third place. Whether you like it or not, Nvidia is becoming even more significant in portfolios — especially for those invested in the $71B Technology Select Sector SPDR Fund, which has risen 23% this year, outperforming both the Nasdaq-100 and S&P 500.

  • By this week’s end, the tech ETF will rebalance, with Nvidia and Microsoft each representing ~21% of the fund — a jump for Nvidia from its previous 6% share.
  • Due to the rebalancing, the fund will acquire over $10B of Nvidia shares — reducing Apple’s share from 22% to ~4.5%.

Buy high, sell higher? Nvidia insiders have capitalized extensively on the company’s rally, selling over $700M in shares this year — the highest in a half-year period since early 2023. Despite the selling spree, no insider purchases have been made since 2020. Combined with the Nasdaq-100 hitting record highs on Monday, it suggests that the AI-driven market rally might be at risk of faltering.
