Slate Money: 2025 Stock Market Performance, AI's Role, and Global Economic Shifts

US Stock Market Performance in 2025

• 📈 The S&P 500 saw a 19% increase in 2025, yet this performance left many investors unsatisfied.
• 🌍 A primary reason for dissatisfaction was that international markets outperformed the US, with European and Asian markets showing stronger gains.
• 📉 For non-dollar-based investors, gains were often diminished due to the decrease in the dollar's value.

The Influence of AI on Market Gains

• 💡 A significant factor contributing to market performance was the perceived reliance on AI-driven companies.
• 🚀 While many companies discussed their AI strategies, the discussion debated whether tech giants like Apple and Google should be classified as pure AI stocks.
• 📊 The Magnificent Seven stocks accounted for a substantial portion of the market's growth, raising questions about market concentration.
• 🔍 The perception of a company as an "AI stock" seemed to drive its market value, even if underlying revenues were not solely AI-related.

Global Economic Trends and Trade

• 🇨🇳 Despite trade war rhetoric, China's stock market saw significant gains, though concerns remain about its investability and underlying debt.
• 🇲🇽 Mexico emerged as a significant beneficiary of trade policies, becoming the US's top trading partner due to favorable tariff rates under USMCA.
• 🇪🇺 European markets, particularly defense stocks, saw a surge due to increased defense spending, partly influenced by geopolitical shifts.

Dealmaking and Berkshire Hathaway's Strategy

• 💰 Global mergers and acquisitions (M&A) reached a record $4.5 trillion in 2025, with significant activity in the US.
• 🏦 Berkshire Hathaway, a trillion-dollar conglomerate, maintained a large cash reserve despite a booming dealmaking market.
• ⏳ With Warren Buffett stepping down at 95, new CEO Greg Abel faces the challenge of deploying this cash, with speculation he might be waiting for a market downturn.
• 🍎 Berkshire Hathaway's significant holdings in Apple have been a major driver of its recent performance.

Broader Economic and Financial Themes

• 💸 A discussion emerged around the idea that "money doesn't mean anything anymore" due to market exuberance and the rise of various asset classes.
• 💰 The K-shaped economy was revisited, highlighting the vast wealth disparity and the flow of money among the ultra-rich.
