  • Warren Buffett Urges Investors to 'Be Greedy When Others Are Fearful' Amid Rising Market Anxiety
    June 7, 2026, 12:11 PM EDT. The CNN Fear & Greed Index shows declining investor confidence, slipping from 71 in early May to 55, nearing fear territory despite markets hitting record highs.

Buffett highlighted in The New York Times that major companies would rebound despite short-term setbacks. Since then, the S&P 500 has gained over 1,000%.
