RTX closed on September 26, 2025, with a 1.77% gain, trading at $0.65 billion in volume, ranking 134th among U.S. equities in terms of liquidity. The stock’s performance followed a strategic review of its trading dynamics and broader market positioning.

Analysts noted the rise could be linked to renewed investor confidence in RTX’s operational efficiency and market share retention in defense and aerospace sectors. The company’s recent restructuring efforts and cost optimization strategies have drawn attention, though no direct earnings or revenue updates were disclosed in the covered period. Market participants observed that the volume surge indicated active institutional participation, though retail activity remained subdued.

For back-testing the top 500 U.S. equities strategy based on daily dollar trading volume, several parameters require clarification. The universe must define whether it includes all listed U.S. stocks or a subset like the S&P 1500. Exclusion criteria for low-priced or ADRs, along with weighting preferences (equal, volume, or dollar), must be specified. Execution timing and cost assumptions—such as zero transaction costs or 2 bps per trade—also need finalization. Additionally, the current back-testing engine requires aggregation of daily holdings into a synthetic portfolio time-series, involving steps like pulling volume data, constructing weights offline, and inputting the resulting P&L series for analysis.

To implement this accurately, confirm the universe scope, rebalancing rules, cost models, and risk controls. Once these details are aligned, the data retrieval and portfolio construction process can proceed systematically to validate the strategy’s historical performance.
