The investment question
You now know EMR reports about 2.2× ROK's revenue, and EMR keeps more of each dollar as net income. Those are the facts. The investment question is what each share price already assumes about their exposure to artificial intelligence, and which evidence in the next filings would prove that assumption wrong.

Read the full researchSEC filing comparison and disclosure evidence
Start with primary filings because fiscal calendars and accounting presentation can make superficially similar quarters incomparable. Both fiscal years end September 30, so annual reports line up, but check segment definitions before comparing growth or margins.
The current verified House and Senate snapshot contains 16 matched transaction rows for EMR and 8 matched transaction rows for ROK. These delayed, range-based disclosures can identify a filing to inspect; they do not establish motive, conviction, or a real-time trading signal.

What this comparison cannot tell you
This page does not contain licensed live prices, a valuation model, earnings estimates, portfolio constraints, or a forecast of future returns. SEC classifications can be broad, company descriptions can lag strategic change, and the latest annual filing may predate a material acquisition or divestiture. Read subsequent quarterly and current reports before making a decision.
A stronger business is not automatically the better stock. Starting valuation, expectations, capital structure, cyclicality, dilution, and the probability of each thesis determine the investment outcome. Use this comparison to frame the work, then verify the numbers in the linked filings and current company disclosures.

EMR vs ROK FAQs
Are EMR and ROK direct competitors?
Not necessarily. Emerson Electric files as Electronic & Other Electrical Equipment (No Computer Equip) and Rockwell Automation as Measuring & Controlling Devices, NEC.

The SEC classifies them differently (Electronic & Other Electrical Equipment (No Computer Equip); Measuring & Controlling Devices, NEC); what connects them is shared exposure to the Artificial intelligence research theme, not a common industry.
