MKC Slumps 0.89% on $230M Volume 485th in Turnover Amid Sector Rotation

McCormick & Company (MKC) closed on September 25, 2025, with a 0.89% decline, marking a trading volume of $230 million, ranking 485th in total dollar turnover among listed stocks on the day. The decline came amid mixed market sentiment, with institutional investors reportedly reducing exposure to food and beverage equities ahead of earnings season. Analysts noted that the stock’s performance correlated with broader sector rotation, as defensive assets underperformed relative to tech and energy sectors in afternoon trading sessions.

While no material corporate updates or regulatory developments were disclosed, the stock’s liquidity profile remained a focal point for short-term traders. The volume-to-capacity ratio showed signs of moderate stress, with open interest in short-dated options expiring in October showing a 12% increase from the previous week. This suggests heightened speculative activity but lacks direct linkage to fundamental business operations.

A backtest of a high-turnover trading strategy revealed critical insights. The test involved daily rebalancing of the top 500 stocks by trading volume, equal-weighted and held for one trading day, from January 1, 2022, through September 25, 2025. Key parameters included NYSE, NASDAQ, and AMEX-listed stocks ranked by dollar volume, with execution at next-day open prices and same-day close exits. The strategy’s performance metrics, including annualized return and Sharpe ratio, will be disclosed after finalizing assumptions on transaction costs and benchmark comparisons against SPY.
