KLA Stock Plummets 6.71% to 75th Largest U.S. Trading Activity Amid Sector Jitters

On October 10, 2025, KLA Corporation (KLAC) closed with a 6.71% decline, marking its largest single-day drop in recent months. The stock traded with a volume of $1.57 billion, securing the 75th highest trading activity on the U.S. equity market. The sharp selloff followed a mixed earnings report earlier in the week, where the company reaffirmed its fiscal year guidance but signaled weaker-than-expected demand in its semiconductor inspection tools segment. Analysts noted that macroeconomic uncertainty and prolonged client budget reviews have dampened near-term visibility for capital equipment providers like KLA.

Investor sentiment was further pressured by broader market concerns over tightening monetary policy and slowing global chip demand. While KLA's long-term growth trajectory remains intact due to its critical role in advanced node manufacturing, short-term volatility is expected to persist as clients delay procurement decisions. The stock's technical indicators now show a breakdown below key support levels, raising questions about near-term stability amid heightened sector-wide jitters.

To ensure that I build the test exactly the way you have in mind, could you please help me pin down a few implementation details? Trading universe—do you want to rank all U.S. listed common stocks every day, or a specific subset (e.g., S&P 500 constituents)? Weighting of the daily basket: equal-weight each of the 500 names, or weight by something else (e.g., market-cap, volume)? Transaction costs & slippage: should we assume zero trading frictions, or apply a specific commission/slippage model? Data frequency: we’ll need daily OHLCV for each stock. Are end-of-day prices acceptable, or do you require intraday execution prices? Risk-free rate/benchmark: any benchmark (e.g., SPY) or risk-free rate you’d like the analysis to compare against?
