ABT vs BSX: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of September 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.

Reading it: BSX is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

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. ABT and BSX 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 ABT and BSX 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.

Abbott Laboratories is a global healthcare company headquartered in North Chicago, Illinois, that discovers, develops, manufactures, and sells health care products in more than 160 countries through four segments: Medical Devices, Diagnostic Products, Nutritional Products, and Established Pharmaceutical Products. Medical Devices, the largest segment at roughly $21.4 billion in 2025 revenue, includes the FreeStyle Libre family of continuous glucose monitors, structural heart products (Navitor, TriClip), electrophysiology systems (AVEIR leadless pacemaker), vascular devices, and heart-failure technologies. Diagnostics contributes roughly $8.9 billion, Nutrition roughly $8.5 billion (anchored by Similac infant formula and Ensure adult nutrition), and Established Pharmaceuticals roughly $5.5 billion in branded generics sold primarily in emerging markets.

Boston Scientific Corporation is a Marlborough, Massachusetts-based medical device company that develops, manufactures, and markets minimally invasive devices used in interventional cardiology, electrophysiology, structural heart, peripheral interventions, endoscopy, urology, neuromodulation, and cardiac rhythm management. It reports through two broad segments: Cardiovascular, which houses the fast-growing electrophysiology business (led by the Farapulse pulsed field ablation system) and the Watchman left-atrial-appendage closure franchise, and MedSurg, which spans endoscopy, urology, and neuromodulation. The company sells into hospitals and physicians across roughly 130 countries and competes at the leading edge of catheter-based and device-based procedures that substitute for more invasive surgery.

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

• ABT drivers: FreeStyle Libre: A Platform, Not Just a Product; Cardiovascular and Electrophysiology Momentum.
• BSX drivers: Farapulse and the Pulsed Field Ablation Wave; Watchman Franchise Expansion.

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: The most acute near-term risk is infant formula litigation: juries have delivered verdicts including a $53 million compensatory award in late March 2026 and a separately upheld $495 million verdict, with hundreds of additional NEC-related cases still pending, and a securities class action filed in 2026 adds a parallel legal exposure track targeting alleged investor misstatements. For BSX, the most immediate concern flagged with 2026 guidance was unanticipated headwinds in electrophysiology, Watchman, and urology, which prompted management to frame organic growth guidance of 6.5% to 8%, below the pace of recent years and a signal that the newest franchises may be decelerating from peak growth rates.

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 ABT if you believe its drivers more; BSX 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 ABT and BSX guides.

ABT. ABT's trailing GAAP P/E of roughly 26x sits below its own 3-year, 5-year, and 10-year historical averages, and is modestly above the Medical Devices and Instruments industry median of roughly 25x, suggesting the market has re-rated the stock from COVID-era growth-premium levels while still assigning a quality multiple. Revenue growth has remained consistently positive in the 5-7% range even as GAAP EPS was pressured in FY2025 by a year-over-year comparison that included elevated one-time items. The FY2026 adjusted EPS guidance of $5.38-$5.58 implies a forward adjusted P/E in the high-teens to low-twenties range at recent share prices, which analysts broadly describe as modestly discounted relative to fundamental fair value estimates.

BSX. Boston Scientific's trailing P/E of roughly 18x sits well below the peer-group average of roughly 34x cited by valuation trackers, a reversal from the sustained premium multiple the stock carried during its high-growth phase. The compression followed a steep share-price decline over the trailing year that coincided with a downward revision to organic growth guidance and disappointing signals in electrophysiology, Watchman, and urology. Net profit margin runs near 17%, and full-year 2026 adjusted EPS growth is guided to 9% to 11%, so the debate is whether the lower multiple reflects fair concern about decelerating growth or an over-correction relative to the franchise's still-double-digit earnings trajectory.

Headline figures (approximate, 2026-06-27 (TTM through Q1 2026; share price data as of June 26, 2026)): ABT shows revenue (ttm) ~$45.1 billion, revenue (fy 2025) ~$44.3 billion (+5.7% YoY), net income (fy 2025) ~$6.5 billion, net profit margin (fy 2025) ~14.7%; BSX shows revenue (ttm) ~$20.6 billion, revenue (fy 2025) ~$20 billion, q1 2026 revenue ~$5.2 billion (+11.6% YoY reported, ~9.4% organic), adjusted eps guidance (fy 2026) ~$3.34 to $3.41 (9% to 11% growth).

ABT and BSX 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. Walnut can show your combined ABT and BSX exposure against your real portfolio. It is not an investment adviser.
