Fair Shares Surge 1.59% as Volume Plummets 25.91% to Rank 159th

Fair (FICO) closed 1.59% higher on October 7, 2025, with a trading volume of $660 million, marking a 25.91% decline from the previous day’s volume and ranking 159th among listed stocks. The security’s performance drew attention amid mixed market conditions and sector-specific dynamics.

Analysts noted that the stock’s modest gain occurred against a backdrop of reduced liquidity, as trading activity waned significantly compared to recent sessions. The decline in volume suggests potential consolidation or short-term profit-taking following prior volatility. However, no major news directly tied to Fair’s operations or broader market catalysts was reported to justify the price movement.

Back-test frameworks for volume-driven strategies require precise parameters. Key considerations include defining the market universe (e.g., U.S. equities or specific indices) and specifying portfolio rebalancing rules—such as equal-weighted daily rebalancing of the top 500 volume stocks. Custom workflows are necessary to aggregate performance metrics accurately, as the strategy involves frequent turnover and execution timing.

Implementation of the back-test demands a structured approach: daily volume rankings must be fetched, baskets constructed, and profit/loss calculations aggregated. Confirmation of the market scope and rebalancing methodology will ensure alignment with the intended strategy’s risk and return profile.
