Meta's $8.58 Billion Volume Plummets 43.88% to Sixth in Equities Trading

On October 7, 2025, Meta (META) closed with a 0.36% decline, trading at a volume of $8.58 billion—a 43.88% drop compared to the prior day’s activity. The stock ranked sixth in trading volume among equities, reflecting mixed investor sentiment amid evolving market conditions.

Recent developments highlight Meta’s strategic focus on AI infrastructure and advertising revenue diversification. The company announced expanded partnerships with cloud providers to enhance its generative AI capabilities, positioning itself to capture a larger share of the enterprise AI market. Additionally, Meta’s quarterly earnings report emphasized stable ad revenue growth in emerging markets, though short-term volatility persists due to macroeconomic uncertainties and regulatory scrutiny.

Analysts noted that Meta’s stock performance remains sensitive to broader tech sector trends. While the company’s long-term growth narrative is intact, near-term challenges include navigating content moderation costs and competition in the AI space. Institutional investors have shown cautious positioning, with mixed activity in options markets suggesting divergent expectations about future price direction.

Regarding the requested back-testing scenario: Constructing a daily-rebalanced, 500-stock, equal-weight portfolio based on highest trading volume (2022–present) requires a multi-security cross-sectional approach. This involves daily ranking of the investable universe by dollar volume, executing 500 simultaneous equal-weighted buys, and aggregating portfolio-level returns. Current tools only support single-security back-testing, necessitating either approximation with an index/ETF or offline custom analysis using exported price/volume data for accurate evaluation.
