Omnicom Climbs 3.79% on $260M Volume 449th in U.S. Market as Volume-Based Strategy Ekes Out 3.77% Return

Omnicom Group Inc. (OMC) rose 3.79% to $76.47 on August 13, 2025, with a trading volume of $260 million, ranking 449th in the U.S. stock market. The advertising agency’s performance aligns with broader sector momentum, though no direct company-specific news directly influenced its share price movement on the day.

A backtest of a strategy involving purchasing the top 500 stocks by daily trading volume and holding them for one day yielded a 3.77% return from 2022 to the present. The approach, which rebalances the portfolio daily, matched the baseline market return over the period. However, the strategy highlights risks tied to liquidity and volatility, as high trading volume does not guarantee sustained performance. The results underscore the challenges of volume-based trading in a dynamic market environment.
