Wall Street is cheering fresh highs as the S&P 500 Index ($SPX) wraps a solid second quarter, closing June 2025 strong. The rally has been powered by cooling inflation, resilient earnings, and fading tariff concerns after April’s policy shock. Just three months back, the market briefly dipped toward bear territory amid geopolitical tensions, China’s AI push, tariff fears, and fiscal uncertainty, keeping investors on edge about the rebound’s staying power.
Despite the S&P rallying over 28% from its April lows of $4,835, the bull run has still left many big names behind. Nearly a third of the index’s stocks still ended the first half of 2025 in the red. UnitedHealth (UNH), a giant in health insurance and managed care services, has plunged 39% so far in 2025. UNH stock has been hit by soaring Medicare Advantage costs, a probe into Medicare fraud, and a sudden CEO exit, making it the index’s fourth-worst performer.
