JPMorgan's 0.81% Rally Overshadowed by 20% Volume Drop 46th Market Rank

On October 3, 2025, JPMorgan Chase (JPM) closed with a 0.81% gain, while its trading volume dropped to $1.86 billion—a 20.46% decline from the prior day—ranking 46th in market volume. The bank’s shares traded with reduced liquidity despite modest price appreciation, reflecting mixed market dynamics for the financial sector.

Recent developments highlighted regulatory scrutiny as the Federal Reserve extended its review of JPMorgan’s fintech partnerships, raising questions about potential compliance costs. Meanwhile, internal restructuring efforts, including workforce reductions in non-core units, were cited as operational headwinds. Analysts noted these factors could influence investor sentiment ahead of the firm’s Q3 earnings release in early November.

To run this back-test rigorously I’ll need to clarify a few practical details first: Universe definition, ranking metric, execution assumptions, and practical constraints. Once those are pinned down I can pull the daily volume data, generate the rebalancing signals, and feed them to a portfolio back-testing engine. Just let me know your preferences on the four points above and I’ll start the data pull and calculation.
