Robinhood Shares Up 2.22% on $4.27 Billion Volume, 15th in U.S. Dollar Trading

Robinhood Markets (HOOD) closed 2.22% higher on Sept. 16 with a trading volume of $4.27 billion, ranking 15th among U.S. equities by dollar volume. The surge followed reports of renewed institutional interest in the platform's zero-commission model, with analysts noting increased order flow from retail investors using automated trading tools. Regulatory updates on clearinghouse reforms also contributed to a broader market risk-on sentiment, though no direct regulatory actions were announced against the brokerage.

Back-test parameters for evaluating volume-driven strategies require precise definitions of stock universes, entry/exit rules, and cost assumptions. The framework includes options for ranking by daily or prior-day volume, equal-weight versus value-weighted allocations, and varying execution timing. Price series definitions and benchmark comparisons will be critical for assessing performance against broad market indices. Implementation details remain pending final confirmation on cost structures and benchmark preferences.
