FactSet Share Price Plummets 0.78% as Trading Volume Drops 37.36% to $200M Ranking 483rd in U.S. Dollar Volume

FactSet (FDS) closed on September 24, 2025, with a 0.78% decline in share price, as its trading volume dropped 37.36% to $200 million, ranking 483rd among U.S. equities by dollar volume. The underperformance reflected broader market dynamics amid shifting investor focus toward sectors with stronger liquidity and growth momentum.

Analysts noted the stock's weak volume performance as a key factor, with reduced institutional activity and limited retail participation contributing to the subdued trading environment. While no material earnings or strategic updates were reported, the decline aligned with a broader trend of underperforming financial data providers facing valuation pressure in a volatile market backdrop.

For the proposed backtesting framework, the current system is constrained to single-asset strategies and event studies. A multi-asset cross-sectional approach involving daily rebalancing across 500 securities remains unfeasible within the existing architecture. Users may either simplify the strategy to single-ticker event analysis or implement a custom Python-based solution using platforms like Zipline or QuantConnect for full portfolio replication, including universe selection, ranking logic, and performance metrics calculation.
