APTV vs MGA: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. APTV and MGA share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined APTV and MGA exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Aptiv (APTV) is a global automotive technology supplier that builds the electrical and electronic architecture, software, and safety systems that modern vehicles run on. Its products span the software-defined vehicle: advanced driver-assistance systems (ADAS) and active safety, connectors and electrical distribution components, high-voltage and data connections for electric vehicles, in-vehicle networking, and the software and compute that tie sensors and controls together. Aptiv sells to nearly every major automaker, so its revenue tracks global vehicle production and the pace at which cars add electronics, safety features, and software content per vehicle. In a major reshaping, Aptiv completed the spin-off of its lower-margin Electrical Distribution Systems (wiring harness) business on April 1, 2026 as a separate company, Versigent (NYSE: VGNT), leaving a smaller, higher-margin New Aptiv focused on intelligent systems and engineered components. Because it supplies the auto industry, Aptiv is cyclical, with results that swing with car sales, but it also carries a secular growth story: the electronic and software content in each new vehicle keeps rising. Headquartered in Dublin, Ireland, Aptiv is widely viewed as a way to invest in the electronics and software layer of the car rather than in any single automaker.

Magna International is a Canadian company and one of the largest automotive suppliers in the world, serving nearly every major global automaker. Its business is organized into four reporting segments: Body Exteriors & Structures (body, chassis, exterior, and roof systems); Power & Vision (powertrain, electronics, mirrors, lighting, mechatronics, and driver-assistance technology); Seating Systems; and Complete Vehicles, which engineers and assembles entire vehicles for automakers on a contract basis. This breadth means Magna's content can appear across many parts of a car regardless of the brand on the badge.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• APTV drivers: Rising electronic and software content per vehicle; A smaller, higher-margin company after the Versigent spin-off.
• MGA drivers: Diversified vehicle content; Margin discipline over volume.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Aptiv is an auto-industry supplier, so its revenue is cyclical and falls when global vehicle production slows in downturns or on supply disruptions. For MGA, magna's biggest risk is cyclicality.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick APTV if you believe its drivers more; MGA if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the APTV and MGA guides.

APTV. Aptiv's financials changed materially in 2026 because the Versigent spin-off removed the lower-margin wiring-harness business, so New Aptiv is smaller with a higher margin profile and prior-year comparisons are not apples to apples. As an auto supplier, its earnings are cyclical and move with global vehicle production, so a valuation that looks reasonable at the top of the auto cycle can look expensive at the bottom. The company used proceeds tied to the spin-off to redeem more than $2 billion of senior notes and to repurchase stock. Figures are approximate and dated; verify current numbers before relying on them.

MGA. These figures are approximate and qualitative, based on recent public reporting, and are not precise or real-time. Auto-supplier results move with production cycles and guidance can change. Always verify current revenue, earnings, dividend, balance-sheet, and guidance details from primary sources before making any decision.

Headline figures (approximate, mid-2026): APTV shows 2026 net sales guidance (new aptiv) ~$12.8 to $13.2 billion, excluding the spun-off EDS business, q1 2026 revenue ~$5.1 billion, up about 5% year over year (GAAP), q1 2026 net income ~$189 million, or about $0.88 per diluted share, 2026 adjusted eps guidance ~$5.70 to $6.10; MGA shows revenue (ttm) Large-scale supplier with tens of billions in annual sales; full-year 2026 guidance was in the low-to-mid $40 billion range, trimmed to reflect softer global production., profitability Profitable with a focus on margin expansion; recent quarters showed earnings growth and beats even as industry volumes declined, per management commentary., balance sheet Established, cash-generative supplier of substantial scale; historically maintains an investment-grade profile. Verify current leverage and liquidity from filings., valuation Typically trades at modest, cyclical-supplier multiples rather than growth-stock levels, reflecting its mature, capital-intensive auto-parts business..

APTV and MGA are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
