Why Comfort Systems Plunged Today

Comfort Systems stock fell 9.36% despite beating revenue and earnings estimates with 53.7% revenue growth and 68.6% EPS growth to $13.91. The decline was driven by CFO Bill George's retirement announcement and broader 'sell the news' sentiment among AI-related stocks, as investors worry about the sustainability of the AI data center build-out beyond 2027. The stock now trades at a reasonable 19.4x forward 2027 earnings, down 38% from its June high.
