ASR vs GAP: 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.

Reading it: GAP 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. ASR and GAP 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 ASR and GAP 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.

Grupo Aeroportuario del Sureste, which operates under the ASUR brand, holds concessions to operate, maintain, and develop 16 airports across the Americas. Its portfolio includes nine airports in southeastern Mexico (led by Cancun, plus Cozumel, Merida, Oaxaca, Veracruz, and others), six airports in northern Colombia through its Airplan unit (including the Medellin metro area hubs), and a 60% stake in Aerostar, which runs San Juan's Luis Munoz Marin International Airport in Puerto Rico. Roughly 58% of revenue comes from Cancun alone, making ASR heavily tied to leisure travel to Mexico's Caribbean coast. Revenue splits between aeronautical fees (charges tied to passengers and aircraft) and a fast-growing non-aeronautical segment (retail leasing, parking, advertising, and commercial services).

Gap Inc. sells clothing under four owned brands and reports each of them separately. Old Navy is the volume engine at roughly $2.0 billion of the $3.5 billion first quarter of fiscal 2026, with the Gap brand at ~$796 million, Banana Republic at ~$431 million and Athleta at ~$270 million. The company ended that quarter with nearly 3,500 store locations across about 35 countries, of which 2,477 were company-operated, and it employs about 79,000 people. Online is ~38% of net sales. Richard Dickson has run the company since 2023, and the turnaround he inherited has been mostly about product, marketing and inventory discipline rather than store expansion.

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

• ASR drivers: Concession-protected airport franchise; Non-aeronautical and commercial growth.
• GAP drivers: The Gap brand is genuinely working; Tariff costs and the merchandise margin path.

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 single largest risk is Cancun concentration: about 58% of revenue derives from one airport tied to leisure travel, so any sustained slowdown in Mexican Caribbean tourism hits results directly. For GAP, guidance for fiscal 2026 was cut to net sales growth of 1% to 2% from 2% to 3%, and management signalled second-quarter sales roughly flat to down 1%, so the top line offers very little cushion.

Pick ASR if you believe its drivers more; GAP 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 ASR and GAP guides.

ASR. Full-year 2025 revenue grew about 19% to roughly Ps.37 billion, though reported earnings declined versus the prior year, partly reflecting the higher concession fee and cost pressures. The stock trades at a mid-to-high-teens price-to-earnings multiple, typical for a regulated infrastructure operator with monopoly-like concessions. Figures are approximate and based on public reporting; the ADR is denominated in US dollars while the underlying results are reported in Mexican pesos.

GAP. Trailing figures cover the four quarters through May 2, 2026 and include the ~$313 million net interchange-litigation gain booked in the first quarter of fiscal 2026, which is why reported EPS of ~$2.52 runs well ahead of the ~$2.30 to ~$2.40 adjusted range guided for the full year. Reported full-year EPS guidance of ~$2.83 to ~$2.93 also carries that gain. On the adjusted number the multiple is closer to ~8.5x, and adjusted operating margin is guided to ~7.3% to ~7.5%, essentially flat with fiscal 2025's 7.3%. Second quarter results are scheduled for August 27, 2026.

Headline figures (approximate, July 2026): ASR shows revenue (fy2025) ~Ps.37 billion (~$2.0B USD), q1 2026 revenue ~Ps.8.9 billion (+0.8% YoY), net income (fy2025) ~Ps.10.5 billion, net debt / ltm ebitda ~0.8x; GAP shows revenue (ttm) ~$15.4B, net income (ttm) ~$962M, diluted eps (ttm, reported) ~$2.52, market cap ~$7.1B at ~$19.65 per share.

ASR and GAP 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.
