Marvell Shares Soar on AI-Driven Momentum $3.53 Billion Volume Ranks 23rd in U.S. Markets

Marvell Technology Group (MRVL) surged 4.64% on September 25, 2025, with a trading volume of $3.53 billion, ranking 23rd among U.S. equities. The semiconductor giant’s strong performance followed renewed investor confidence in its AI infrastructure solutions and supply chain resilience amid industry-wide component shortages.

Analysts highlighted Marvell’s recent strategic partnerships in edge computing and data center expansion as key drivers. The company’s ability to secure long-term contracts with hyperscale cloud providers has positioned it as a beneficiary of sustained demand for high-performance computing chips. Additionally, improved inventory management practices have reduced production bottlenecks, reinforcing positive sentiment.

To set up a rigorous back-test I need to pin down a few practical details your description doesn’t yet specify. Once these are clarified I can build the data-gathering plan and run the back-test for you.

Market universe • Do you want to scan the entire U.S. listed equity universe (NYSE + NASDAQ + AMEX), or a different region/universe?

Rebalancing logic • Each trading day we rank stocks by that day’s dollar trading volume and buy the top 500 names. • Positions are closed after one trading day (i.e., buy day T, sell day T + 1). • Equal-weight across the 500 names—acceptable?

Trade-price convention • Enter at the day’s close and exit at the next day’s close (standard for daily turnover volume strategies), unless you prefer open-to-open or another convention.

Transaction costs & slippage • Should we include a round-trip cost assumption (e.g., 5 bp each side), or treat returns as gross of costs?

Please let me know (or approve the suggested defaults). With that information I’ll generate the retrieval plan, gather the data, and run the back-test from 2022-01-03 through today.
