Parker Hannifin (PH) closed at a 2.99% decline on October 10, 2025, with a trading volume of $0.43 billion, ranking 297th in market activity for the day. The stock’s movement appeared linked to sector-specific dynamics and operational updates disclosed in recent reports.

Analysts highlighted mixed signals in the firm’s third-quarter outlook, with revised revenue guidance reflecting cautious demand assumptions in industrial markets. Management emphasized ongoing cost optimization efforts, though investors remained skeptical about near-term margin expansion. Supply chain constraints in key manufacturing regions also contributed to short-term volatility.

To run an accurate back-test I need to clarify a few practical details that affect both data collection and the portfolio-level calculations: 1. Universe • Do you want to consider all U.S.–listed common stocks (NYSE + NASDAQ + AMEX) or a narrower group (e.g., S&P 500 constituents)? 2. Weighting & capital allocation • Should the top-500 names be held in equal dollar weights (i.e., 0.2 % of capital each) or some other weighting scheme? • Are you assuming fully invested capital every day or allowing residual cash if fewer than 500 symbols trade on a given day? 3. Transaction costs & slippage • Should we include estimated trading costs (commissions, bid/ask spread, price impact), or assume frictionless execution at the close? 4. Benchmark (optional) • Would you like the strategy’s results compared with a benchmark such as SPY or an equal-weighted market portfolio? Once I have these details I can put the data-gathering and back-testing pipeline in motion.
