Parker Hannifin’s 0.76% Surge Lifts $260M Volume, Secures 404th U.S. Stock Rank

Parker Hannifin (PH) rose 0.76% on Sept. 26, with a trading volume of $260 million, ranking 404th among U.S. stocks. The industrial manufacturer’s performance was influenced by market-moving news related to its operational strategy and sector positioning.

Recent developments highlighted include a strategic partnership to expand its fluid handling solutions in energy infrastructure projects. Analysts noted the move could strengthen PH’s market share in high-growth sectors, though no immediate earnings impact was disclosed. Additionally, the company reaffirmed its focus on cost optimization amid rising input costs, aligning with broader industry trends in capital efficiency.

To run this back-test robustly I’ll need to pin down a couple of details:

1. Universe • Should “top 500 stocks by daily trading volume” be taken from all U.S. listed equities, an index universe (e.g., S&P 1500 / Russell 3000), or another regional market?

2. Rebalancing logic • Do we rebalance every trading day (i.e., each day we rank volumes, buy the day’s top-500 at the close, and exit all positions at the next day’s close)? • Is equal weighting acceptable for the 500 holdings?

3. Transaction considerations • Should we include trading costs or slippage, or keep the test frictionless?

Once I have this information I can generate the data-retrieval plan and run the back-test.
