- Scale: TEL's $17.3B of revenue is about 1.9× STX's $9.1B.

The investment question
You now know TEL reports about 1.9× STX's revenue, and STX 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 tariffs & trade, and which evidence in the next filings would prove that assumption wrong.

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.
