Moody's Shares Dip 0.77% with $440M Volume Ranking 282nd as Insiders Sell and High-Liquidity Strategy Surpasses 166% Return

On August 5, 2025, Moody’s Corp (MCO) closed at $518.96, down 0.77%, with a trading volume of $440 million, ranking 282nd in daily liquidity. The stock traded at a price-to-earnings ratio of 43.83, above its historical median and the industry benchmark of 20.32.

A recent insider transaction highlighted ongoing selling pressure. Stephen Tulenko, President of Moody’s Analytics, sold 300 shares on August 4, marking his 32nd sale in the past year. Over the same period, no insider purchases were recorded. Tulenko has offloaded 13,000 shares since 2024, reflecting a consistent trend of insider divestment. The transaction occurred at $518.96, aligning with the stock’s recent valuation metrics but signaling caution among top executives.

Backtesting a high-volume trading strategy revealed significant outperformance: purchasing the top 500 most liquid stocks and holding for one day generated a 166.71% return from 2022 to 2025, surpassing the benchmark by 137.53%. This underscores the role of liquidity concentration in short-term gains, particularly in volatile markets where high-volume stocks react swiftly to price shifts.
