Emersons 129% Surge on 370M Volume Driven by Industrial Automation Push and Energy Infrastructure Gains Ranked 309th in Market Activity

On October 3, 2025, Emerson (EMR) rose 1.29% with a trading volume of $0.37 billion, ranking 309th in market activity. The stock's movement coincided with reports highlighting its strategic focus on industrial automation solutions and recent contract awards in energy infrastructure projects. Analysts noted the firm's emphasis on high-margin segments within its process management division as a key driver for investor confidence.

Recent disclosures emphasized Emerson's expansion into renewable energy systems, including a multi-year partnership to integrate smart grid technologies. The company also reiterated its commitment to cost optimization initiatives, which have historically supported consistent free cash flow generation. These operational updates were cited as factors reinforcing long-term growth expectations among institutional investors.

To run this back-test accurately I need to pin down a few practical details about how the daily portfolio is formed and how trades are priced. Could you confirm or adjust the following assumptions? Market universe: All U.S. listed common stocks (NYSE + NASDAQ + AMEX), excluding ETFs, preferreds, etc. Volume ranking metric: Rank each stock by the share-volume traded during that day (not dollar volume). Trade timing & pricing: We form the list after the market closes on day t, buy all 500 stocks at the next day’s open (t + 1), hold until that day’s close, then liquidate. Positions are equal-weighted. Transaction costs / slippage: Assume zero unless you’d like to include a specific cost per trade. If any of these need to change, please let me know. Once confirmed, I’ll run the data fetch and back-test from 2022-01-03 (first trading day of 2022) through today.
