Palantir Slumps 1.64% Despite Ranking Eighth in U.S. Trading Volume

On September 24, 2025, Palantir Technologies (PLTR) closed with a 1.64% decline, marking its lowest intra-day performance since mid-August. Trading volume totaled $8.17 billion, representing a 27.99% drop from the previous day’s activity. The stock ranked eighth in overall trading activity across U.S. equities despite the pullback, reflecting sustained institutional engagement in the AI analytics sector.

Recent developments highlight a mixed outlook for Palantir’s near-term trajectory. A government contract update revealed delayed negotiations for a multi-year data infrastructure project, with officials citing internal budgetary constraints. Meanwhile, a partnership with a major cloud provider was confirmed but scaled back from initial expectations, with the agreement now focusing on co-development rather than exclusive deployment. Analysts noted these adjustments suggest cautious optimism rather than transformative momentum.

Technical indicators show PLTR testing key support levels near its 50-day moving average, with short-term traders closely monitoring volume patterns for reversal signals. Options market positioning remains balanced, though put options have seen a 12% increase in open interest over the past week. No material earnings revisions or regulatory updates have emerged to directly impact valuation metrics.

I understand you’d like to evaluate a strategy that, every trading day from January 1, 2022, through today, buys an equal-weight portfolio consisting of that day’s 500 highest-volume U.S. stocks, then closes the entire position the following day. At the moment I don’t yet have a pre-built dataset containing the daily “top-500-by-volume” list across the U.S. equity universe. Proceeding would require either a ready-to-use ticker list for each date in the back-test window or authorization to process raw volume data—a capability not yet configured in my current toolset. Could you clarify whether you can supply the required data files or prefer an alternative approach?
