Ameriprise Financials Trading Volume Plummets 47.59 to 497th Rank Despite 1.07 Gains Amid Sector Liquidity Woes

Ameriprise Financial (AMP) saw a trading volume of $0.20 billion on September 18, 2025, a 47.59% decline from the previous day, ranking it 497th in terms of trading activity among stocks listed that day. The stock closed with a 1.07% gain, outperforming broader market trends.

Reduced liquidity in the asset management sector contributed to the muted volume. Analysts noted that seasonal portfolio rebalancing and cautious positioning ahead of earnings season likely tempered institutional activity. The firm’s fixed-income platforms remain under pressure from rising interest rates, though its wealth management segment continues to attract inflows.

To run this back-test accurately, I need to pin down a few practical details: Universe—screen the entire U.S. stock universe (all common stocks listed on NYSE + NASDAQ) or a different market? Volume definition—rank by “dollar volume” (price × shares traded) or by raw share volume? Trade mechanics—buy at today’s close and exit at tomorrow’s close (standard one-day holding period), or another timing (e.g., buy next day’s open, exit next day’s close)? Position sizing—equal-weight each of the 500 names, or weight by volume, market-cap, etc.? Transaction costs / slippage—should we include any round-trip cost assumption? (Typical default: 1–5 bps per side.)

Once these parameters are finalized, the daily rotation back-test will run from January 3, 2022, through today’s date to evaluate strategy performance.
