NET vs VIV: 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: VIV 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. NET and VIV 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 NET and VIV 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.

Cloudflare operates a global cloud network that sits between internet users and the websites and applications they access, providing performance, security, and reliability services. Its core offering started as a content delivery network and DDoS protection: Cloudflare caches content close to users and absorbs malicious traffic before it reaches customer servers. Over time it has expanded into a broad platform spanning web application firewalls, zero-trust security (replacing traditional VPNs and securing employee access), DNS, bot management, and a developer platform for running code and storing data at the network edge (Workers, R2 object storage, and related serverless products). Cloudflare's network spans hundreds of cities worldwide, giving it scale advantages in latency and security intelligence. It serves millions of customers from free-tier websites to large enterprises, monetizing through subscriptions and usage-based pricing as customers adopt more products. The company is positioning its edge network and Workers AI platform to run AI inference close to users. Founded in 2009 and headquartered in San Francisco, Cloudflare is a high-growth infrastructure-software company expanding from security and performance into edge computing and AI.

Telefonica Brasil, which operates under the Vivo brand, is the largest telecommunications company in Brazil. It provides mobile voice and data service, fiber and fixed broadband, pay TV, and digital services to consumers and businesses across the country. The company is the mobile market leader with roughly 103 million mobile accesses and about a 38% share, and it has been aggressively expanding fiber-to-the-home, reaching around 31 million homes passed and roughly 7.8 million connected homes by the end of 2025. Vivo makes money primarily from recurring monthly mobile and broadband subscriptions, with postpaid mobile and FTTH fiber the main growth engines while legacy fixed voice and DSL decline.

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

• NET drivers: Expanding platform and land-and-expand; Global edge network as a moat.
• VIV drivers: Market-leading mobile franchise; Fiber (FTTH) 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: Cloudflare trades at a high revenue multiple that embeds years of strong growth, leaving the stock vulnerable to multiple compression if growth decelerates or software valuations reset. For VIV, as an ADR, VIV carries meaningful currency risk: even when Vivo grows in Brazilian reais, a weaker real reduces the dollar value of both the share price and the dividend for US holders.

Pick NET if you believe its drivers more; VIV 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 NET and VIV guides.

NET. Cloudflare trades at one of the higher revenue multiples in infrastructure software, reflecting durable growth, a global-network moat, and optionality in edge compute and AI rather than near-term GAAP earnings. The valuation is sensitive to growth deceleration and broad software-multiple swings. The premium has compressed sharply during software-sector resets and re-rated when growth and free cash flow surprised positively.

VIV. VIV trades as a high-yield emerging-market telecom, valued more on its dividend and cash generation than on growth. The company distributes essentially all of its net income to shareholders, so the ADR behaves like an income holding whose dollar return depends on both operating results and the Brazilian real. All figures are approximate and as of July 2026.

Headline figures (approximate, early 2026): NET shows revenue (ttm) ~$1.8 billion, revenue growth ~25-30% year over year, gross margin ~75-78%, gaap profitability Around breakeven to modest losses; non-GAAP profitable; VIV shows net operating revenue (fy2025) ~R$59.6 billion (~$11 billion), net income (fy2025) ~R$6.2 billion (~$1.1 billion), revenue growth (fy2025) ~7% year over year, dividend yield (adr) ~5% to 6%.

NET and VIV 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 NET and VIV exposure against your real portfolio. It is not an investment adviser.
