KLA Stock Plunges 8.42% on $1.83 Billion Surge in Volume Ranks 35th in U.S. Liquidity as Second-Worst Performer in Major Indices

KLA Corporation (KLAC) saw a significant decline on August 15, 2025, closing 8.42% lower as trading volume surged to $1.83 billion—a 91.56% increase from the previous day—ranking it 35th among U.S. equities by liquidity. The selloff marked the stock’s first loss following a three-day upward streak, with shares trading near their lowest intraday level since mid-August. Market participants noted the drop aligned with broader sector pressures and technical indicators suggesting short-term volatility.

Analysts highlighted the stock’s proximity to key support levels, with prices nearing the 52-week low of $576.53 set in April. While KLA remains 39.34% above its 2025 year-to-date low, the recent pullback raised questions about sustainability of its rally. The decline also positioned KLAC as the second-worst performer in both the S&P 500 and Nasdaq 100 indices for the day, amplifying concerns about near-term momentum.

Backtesting of a strategy focused on high-volume stocks from 2022 to 2025 showed a 1-day return of 0.98% and a cumulative gain of 37.61%. The approach demonstrated stability but underscored the conservative nature of volume-driven short-term trading, with returns trailing those of higher-risk alternatives.
