GALICIA Soars 21% on $220M Surge to 477th Rank Amid Institutional Mystery

, 2025, , . . Recent market activity appears to reflect renewed institutional interest amid strategic operational adjustments.

Analysts note that the sharp volume spike suggests potential short-term momentum, though sustainability remains untested. The stock's performance diverges from broader market trends, indicating sector-specific catalysts may be at play. No direct earnings or regulatory updates were reported to explain the move.

To run this back-test accurately I need to pin down a few implementation details — once these are settled I can pull the data and execute the back-test for you. Universe • Do you want all U.S. listed common stocks, or a narrower list (e.g. S&P 500 constituents, Russell 3000, etc.)? Ranking • To avoid look-ahead, the usual practice is to rank stocks by yesterday’s volume, then enter positions at today’s open (and exit at tomorrow’s open or close). Is this acceptable, or would you prefer a different timing rule? Weighting & rebalancing • Equal-weight across the 500 names each day? Or volume-weighted / ? Trading frictions (optional) • Should I include an estimate for slippage/commissions, or assume zero costs? Once I have this information I can generate the signal file and run the one-day-holding back-test from 2022-01-01 to today.
