NSANY vs STLA: 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.

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. NSANY and STLA 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 NSANY and STLA 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.

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

• NSANY drivers: Re:Nissan cost reduction; North America recovery and US production.
• STLA drivers: Turnaround under a new CEO; Very low valuation, with capital returns on hold.

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 risks are large and specific. For STLA, the dominant risk is cyclicality: automakers' profits swing sharply with the economy, consumer confidence, and interest rates, so a downturn can quickly hurt sales and earnings.

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 NSANY if you believe its drivers more; STLA 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 NSANY and STLA guides.

NSANY. These are company-level figures, because the ADR represents 2 ordinary shares and per-share numbers convert through both the ratio and the yen. At roughly $6.5 to $7 billion of market value against about $82 billion of annual revenue, Nissan trades at under a tenth of a year's sales and well below book value, levels typical of a distressed automaker. Trailing earnings are negative, and on the ~¥20 billion fiscal 2026 net profit target the forward P/E would look very high, so earnings multiples say little here. The valuation instead reflects doubt about whether margins recover and how much of the balance sheet belongs to creditors and the finance arm rather than shareholders.

STLA. At under ~0.1x sales and ~0.2x book, the market is pricing Stellantis for continued losses and cash burn rather than a recovery, which is why a forward multiple under ~4x on 2027 estimates draws little support. Second-quarter profit fell short of consensus and the shares have lost ~23% over three months. Third-quarter results on October 28, 2026 come with consensus for a small loss of about ~$0.18 per share on ~EUR 35.7 billion of revenue.

Headline figures (approximate, October 2026): NSANY shows revenue (ttm) ~¥12.3 trillion (~$82B), operating profit (ttm) ~¥0.2 trillion, margin under 2%, net income (ttm) ~¥-414 billion loss, market cap ~$6.5B to $7B (ADR near ~$3.60); STLA shows revenue (ttm) ~EUR 161 billion; Q2 2026 revenue ~EUR 43.5 billion, up ~13% year over year, margins ~6.6% gross, ~2.2% operating (TTM); Q2 2026 operating margin ~1.8%, net income ~EUR 19.5 billion TTM net loss, after a ~EUR 22.3 billion loss in 2025; Q2 2026 net profit ~EUR 266 million, forward p/e ~3.7x on 2027 consensus EPS of ~$1.20; no trailing P/E (loss).

NSANY and STLA 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.
