The U.S. stock market witnessed a strong rally on May 14, 2025, with top-performing stocks showing double-digit gains across sectors such as e-commerce, biotech, AI computing, clean energy, and satellite communications. Investor sentiment turned decisively bullish following a softer-than-expected core CPI print, dovish commentary from Federal Reserve officials, and early signs of tariff de-escalation between the U.S. and China. Institutional flows tilted toward growth and innovation, with retail momentum fueling smaller-cap names. Below is a detailed breakdown of all 24 top U.S. stock market gainers for May 14, including performance analysis, volume data, valuation metrics, and investor sentiment.

With a market cap of just $155.6 million and no current P/E ratio due to losses, Newegg’s surge appears driven by short covering, algorithmic interest, and speculative retail positioning following improved e-commerce sales data in April.
