SF vs YMM: 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. SF and YMM 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 SF and YMM 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. Walnut is not an investment adviser.

Full Truck Alliance Co. Ltd. runs the largest digital freight-matching network in China. It was formed from the 2017 merger of Yunmanman and Huochebang, the two apps that had separately digitized the country's roadside truck-stop marketplaces, and it listed on the NYSE in June 2021 at $19 per ADS. Shippers post full-truckload and less-than-truckload loads, truckers bid or accept them, and the platform takes a cut. Revenue arrives through four channels: freight matching commissions (transaction services), membership subscriptions sold to both shippers and truckers, credit solutions extended to drivers for fuel and vehicle purchases, and a freight brokerage line where the company sits in the middle of the transaction as principal. The last of those books gross revenue at very thin margins and is being restructured, which matters a lot for how the headline numbers read.

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

• SF drivers: Wealth management fee base; Investment banking and capital markets recovery.
• YMM drivers: Take rate, not user growth; Network effects in a fragmented market.

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: As a broker-dealer and investment bank, Stifel is cyclical and its institutional revenue can fall sharply when M&A and underwriting activity dries up. For YMM, the structural risks come first.

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 SF if you believe its drivers more; YMM 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 SF and YMM guides.

SF. Stifel posted record first-quarter 2026 net revenues near $1.48 billion, with net income to common of about $242 million, helped by strong investment banking, asset management, and a gain on the sale of Stifel Independent Advisors. Non-GAAP return on tangible common equity was reported near 24.8 percent. At a mid-teens price-to-earnings multiple, the shares are valued in line with other mid-cap wealth and capital-markets firms rather than at a growth premium.

YMM. Full Truck Alliance reports in Chinese renminbi, so most of the confusion around this ticker comes from currency: a screen showing ~12.64B revenue against a ~$9.2B market cap implies a fraction of one times sales, when the real ratio on converted revenue of ~$1.8B is closer to five times. On earnings the arithmetic is less exotic: ~$9.2B of market value against ~$640M of FY2025 GAAP net income is roughly the mid-teens, and stripping out the ~$4.4B net cash position takes the operating business to high single digits. The offsetting fact is that Q1 2026 profit fell year over year and Q2 guidance points to a revenue decline, so the trailing multiple is being paid on a number that is not currently compounding.

Headline figures (approximate, JULY 2026): SF shows net revenues (ttm) ~$5.6B, q1 2026 net revenue ~$1.48B (up ~18% YoY), q1 2026 diluted eps ~$1.48, market cap ~$12B; YMM shows revenue (ttm) ~RMB 12.6B (~$1.8B). Screeners often show ~12.64B without converting from renminbi, which overstates the USD figure by about 7x, fy2025 revenue growth ~+11.1% year over year, to ~RMB 12.49B (~$1.79B), fy2025 net income ~RMB 4.46B (~$640M), up ~42.8%; free cash flow ~RMB 4.5B, q1 2026 Net revenues ~RMB 2.85B (~+5.5%); net income ~RMB 994M and non-GAAP adjusted net income ~RMB 1.20B, both below the year-ago quarter.

SF and YMM 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 SF and YMM exposure against your real portfolio. It is not an investment adviser.
