Rockwell Automation, Inc. vs TERADYNE, INC., two Scientific Instruments stocks. A side-by-side on valuation, growth, margins, returns, and what each price is betting.
Both prices bet on industrial technology cycles, and neither is shy: Teradyne at 80.9 times earnings needs the AI chip-test boom to keep steepening; Rockwell at 49.5 times needs factory-automation spending to reaccelerate from its digestive phase. Teradyne's economics currently justify more of its premium, a 36.9% operating margin and 19.3% return on assets against Rockwell's 23.7% and 9.7%. Rockwell carries a full turn of debt and pays a 1.1% dividend; Teradyne is debt-free and pays almost nothing. The multiples say the market trusts chip-test momentum over automation recovery by 31 turns; the balance sheets say Rockwell has less room for the trust to be wrong.
