FHN Slumps 4.99% as 490M Volume Ranks 257th in Market Doldrums

On October 10, 2025, First Horizon (FHN) closed at a 4.99% decline, with a trading volume of $490 million, ranking 257th in market activity. The stock's performance was influenced by sector-specific dynamics amid evolving market conditions.

Analysts noted that the decline reflected broader challenges in the regional banking sector, including regulatory pressures and shifting interest rate expectations. While no direct corporate announcements impacted FHN, market participants attributed the move to macroeconomic sentiment and risk-off trading patterns observed during the session.

To run this test rigorously I need a bit more detail: 1. Universe Which market do you want to rank (e.g., all U.S. listed stocks, only S&P 500 constituents, a specific exchange, etc.)? 2. Ranking metric “Daily trading volume” – do you want to rank by (a) raw share volume or (b) dollar volume (shares × price)? 3. Entry & exit prices Should we simulate buying at today’s close and selling at tomorrow’s close (Close→Close), or use opens, or something else? 4. Transaction costs / slippage Include any? If not specified I will assume zero. Once I have these points I can assemble the data-retrieval plan and run the back-test for 1-Jan-2022 through today.
