Vistra (VST) closed with a 0.33% decline on October 3, 2025, trading at $X.XX per share. The stock recorded a trading volume of $1.09 billion, ranking 95th among U.S. equities in terms of daily turnover. The move followed mixed market sentiment and broader sector rotation, though no specific corporate announcements directly impacted the stock.

Analysts noted that the stock’s performance aligned with subdued energy sector activity, as investors remained cautious ahead of potential regulatory updates. While no earnings reports or strategic partnerships were disclosed, the volume surge suggested increased short-term positioning amid macroeconomic uncertainty. However, the lack of catalysts limited momentum, keeping the stock near its recent trading range.

For back-testing a daily-rebalanced 500-stock portfolio, practical constraints require defining a clear universe such as the S&P 1500 or Russell 3000. Ranking by previous day’s dollar volume and rebalancing at the next open or close must be confirmed. Weighting approaches—equal or volume-proportional—alongside commission and slippage assumptions, need specification. The current toolset supports single-ticker analysis, necessitating a custom portfolio layer for true 500-stock rotation. Alternatives include using an ETF benchmark or narrowing to a static basket of high-volume stocks for testing within existing limitations.
