Summary

The S&P 500 is projected to close 2025 with a gain of over 17%, marking the third consecutive year of a bull market, largely driven by enthusiasm for artificial intelligence (AI). AI-related stocks, including those in data storage and data center infrastructure, have led the charge, with hyperscalers like Microsoft and Amazon pledging over $440 billion for AI expansion, benefiting companies like Sandisk and Western Digital. Palantir Technologies and Warner Bros. Discovery emerged as top performers, with significant gains fueled by AI interest and takeover speculation, respectively. New S&P 500 additions like Robinhood and AppLovin also saw triple-digit increases, though some newcomers struggled. Conversely, consumer staples, retail, and managed care sectors faced headwinds from economic uncertainty, tariffs, and policy ambiguity under the Trump administration. Stocks like Chipotle, Lululemon, and Molina Healthcare saw substantial declines, though some investors see potential for recovery in undervalued health insurance stocks.
