AAPL vs CMCSA: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 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: CMCSA 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. AAPL and CMCSA 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 AAPL and CMCSA 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.

Apple (AAPL) designs and sells consumer hardware, software, and services. The iPhone is its largest product by revenue, complemented by Mac computers, iPad tablets, and the wearables category (Apple Watch, AirPods). The fastest-growing and highest-margin part of the business is Services: the App Store, iCloud, Apple Music, Apple TV+, AppleCare, advertising, and payments. Apple's strategy centers on a tightly integrated ecosystem where hardware, the operating systems (iOS, macOS, watchOS), and services reinforce each other and create high switching costs. The company designs its own silicon (the A-series and M-series chips) and outsources manufacturing primarily to partners like TSMC and Foxconn. Founded in 1976 and headquartered in Cupertino, California, Apple is one of the most valuable companies in the world, with a market cap of about $5.0 trillion as of October 16, 2026, and returns enormous cash to shareholders through buybacks and a growing dividend. Trailing twelve-month revenue reached about $467 billion through the June 2026 quarter, up from $416 billion in fiscal 2025, and the shares closed at $345.10 on October 16, 2026, up about 27% year to date and about 40% over one year. In October 2026 the launch of the iPhone Duo, a $1,999 foldable, drew strong preorders, with reports of delivery dates pushed to December and into 2027.

Comcast is a global media and technology company built on three main pillars. Its Connectivity and Platforms business, anchored by Xfinity, is one of the largest US broadband and cable providers, selling high-speed internet, video, mobile (Xfinity Mobile), and home services to tens of millions of households, plus business connectivity. Its Content and Experiences business includes NBCUniversal, which owns the NBC broadcast network, cable networks (USA, Bravo, MSNBC, CNBC), the Peacock streaming service, Universal Pictures film studio, and Universal theme parks worldwide. Comcast also owns Sky, a major European media and broadband operator. The company makes money primarily from recurring broadband and connectivity subscriptions, which are its most profitable and stable revenue, supplemented by advertising, content licensing, box-office and streaming revenue, and theme-park admissions. Comcast is headquartered in Philadelphia and generates substantial free cash flow that funds dividends and buybacks.

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

• AAPL drivers: Services growth and margin; Installed base, switching costs and the foldable cycle.
• CMCSA drivers: Broadband cash engine; Wireless and convergence.

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: iPhone is still the majority of revenue, so any slowdown in smartphone replacement cycles or weakness in China, a large and competitive market, hits results directly. For CMCSA, comcast's core video business is in secular decline as cord-cutting erodes traditional cable-TV subscribers, and broadband subscribers keep shrinking under heavy competition from fiber overbuilders (AT and T, others), fixed-wireless from T-Mobile and Verizon, and newer satellite mobile and internet offers.

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 AAPL if you believe its drivers more; CMCSA 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 AAPL and CMCSA guides.

AAPL. Apple's multiple has expanded through 2026: the shares trade near 40x trailing earnings as of mid-October, up from about 33x early in the year, and sit above the average analyst target of about $329. The premium rests on reaccelerating revenue, record margins, roughly $108 billion of annual free cash flow and buybacks that keep shrinking the share count, so the November 2 report and early iPhone Duo supply will test whether earnings can grow into the price.

CMCSA. At roughly six to seven times earnings and a ~6% yield, Comcast is priced for continued decline in its core broadband business, which shrank its market value to under ~$80 billion in October 2026. The bull case rests on ~$12.7 billion of trailing free cash flow, parks and Peacock growth, and the pricing reset stabilising subscribers; the bear case is that lower ARPU and free lines compress margins faster than retention improves. Third-quarter results on 22 October 2026 (consensus ~$0.99 EPS) are the next read.

Headline figures (approximate, October 2026): AAPL shows revenue (ttm) ~$467 billion (June 2026 quarter up ~16% YoY), gross / operating margin ~48.7% / ~32.6%, net income (ttm) ~$129 billion (EPS ~$8.72), p/e (trailing / forward) ~40x / ~36x; CMCSA shows revenue (ttm) ~$124.9 billion; Q2 2026 ~$29.94 billion, -~1.2% y/y, operating margin ~17% latest; ~14.7% trailing per Trefis, down from ~18.1%, net income (ttm) ~$11.2 billion (~$3.10 EPS), p/e trailing / forward ~7.2x / ~6.2x.

AAPL and CMCSA 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 AAPL and CMCSA exposure against your real portfolio. It is not an investment adviser.
