The article analyzes the performance of Alphabet (GOOGL) relative to other major S&P 500 constituents as of late 2026. While the broader index has risen approximately 12% year-to-date, Alphabet's Class A shares have significantly underperformed, gaining only about 2%. The text notes that Alphabet, along with Microsoft and Amazon, comprises roughly 15% of the Vanguard S&P 500 index fund, making their upcoming earnings reports on October 28 critical for the overall fund performance. Alphabet's stock price is currently trading approximately 21% below its 52-week high, distinguishing it from peers like Apple and Nvidia which have driven much of the index's recent gains. The author highlights that Alphabet, Microsoft, and Amazon are scheduled to report earnings within a two-day window in late October, creating a concentrated risk event where sharp reactions could move the entire S&P 500 fund by roughly one percentage point. The piece concludes with investment advice suggesting that investors should not alter their positions in broad market funds like the S&P 500 before these reports are released. The author argues that the remaining portion of the fund has performed well independently, and the weight of Alphabet's underperformance is a temporary divergence rather than a reason to exit the index entirely.
