From each company's latest annual SEC filing. Fiscal years can end on different dates.
Advanced Micro Devices (AMD) is the larger business by reported revenue: $34.6B in its fiscal year ended Dec 2025, about 1.5× APH's $23.1B (fiscal year ended Dec 2025). AMD's net margin was 12.5% and APH's 18.5%. The SEC places them in related industries (Semiconductors & Related Devices; Electronic Connectors), and both map to the Tariffs & trade research theme.
Figures come from each company's own SEC filings. This page compares the businesses; it is not a price target or a verdict.

Overlap is drawn from SEC classifications and Yield Theory research themes. It is not evidence that the companies sell to the same customers or compete product for product.
AMD designs CPUs and GPUs for PCs, servers, and gaming consoles, positioning itself as the primary challenger to both Intel and NVIDIA. Its data-center accelerators are central to its ambitions in the AI compute market.
Amphenol makes electronic connectors, cables, and sensors used across communications, industrial, automotive, and defense systems.
Company-specific drivers maintained by Yield Theory. Use them to decide which filing deserves deeper work; they are not predictions.
We have not yet published a company-specific driver list for APH. The primary source is Item 1 (Business) and Item 1A (Risk Factors) of its 10-K filed 2026-02-11.
You now know AMD reports about 1.5× APH's revenue, and APH 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, including “Data Center revenue from EPYC server CPUs and Instinct GPU accelerators” at AMD, and which evidence in the next filings would prove that assumption wrong.

Read the full researchStart with primary filings because fiscal calendars and accounting presentation can make superficially similar quarters incomparable. AMD's fiscal year ends December 26, while APH's ends December 31. Normalize the reporting periods before comparing growth, margins, capital intensity, or guidance.
The current verified House and Senate snapshot contains 50 matched transaction rows for AMD and 10 matched transaction rows for APH. These delayed, range-based disclosures can identify a filing to inspect; they do not establish motive, conviction, or a real-time trading signal.
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.
Not necessarily. Advanced Micro Devices files as Semiconductors & Related Devices and Amphenol as Electronic Connectors. The pair is compared because both map to the Tariffs & trade research theme, not because the filings show head-to-head competition.

There is no context-free winner. Compare the operating exposures, filing evidence, valuation, balance sheet, and risks against the specific thesis you are testing. This page deliberately does not turn a static profile into a buy or sell recommendation.
No. Yield Theory does not republish unlicensed real-time market data.
