BYD vs CYATY: 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. BYD and CYATY 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 BYD and CYATY 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.

Boyd Gaming Corporation operates casinos and gaming entertainment properties across the United States, organized into segments spanning the Las Vegas Locals market, Downtown Las Vegas, the Midwest and South, plus a Managed and Other category and an Online segment. The regional and locals-focused footprint, rather than the Las Vegas Strip, is the core of the business: these properties draw repeat local and drive-in visitors and historically produce steady, high-margin cash flow. In Q1 2026 the company reported revenue of ~$997.4 million with company-wide property margins above ~39%, and the Midwest and South segment grew revenue ~4.1% year over year. The second quarter of 2026 brought revenue of ~$1.03 billion, roughly flat year over year, and adjusted EPS of ~$1.93 against a ~$1.89 estimate, after a first-quarter miss (~$1.60 versus ~$1.71).

Contemporary Amperex Technology Co., Limited (CATL), based in Ningde, China, makes lithium-ion batteries for electric vehicles and for stationary energy storage. It sells cells and packs to most major automakers, including Tesla, BMW, Mercedes-Benz, Volkswagen, Li Auto, Xiaomi and many other Chinese brands, and makes money mainly on the volume of gigawatt-hours it ships. It sold about 661 GWh of batteries in 2025 and held roughly 40% of the global EV battery market in 2026, more than double BYD in second place. Power batteries brought in about RMB 192 billion in the first half of 2026 and energy storage about RMB 53 billion, with the rest from materials, recycling and licensing (including the LFP technology Ford uses in Michigan). CATL trades primarily in Shenzhen (300750) and, since May 2025, in Hong Kong (3750); CYATY is an unsponsored ADR quoted over the counter in the US.

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

• BYD drivers: Regional and locals-market stability; Online gaming and the FanDuel agreement.
• CYATY drivers: Energy storage as a second engine; EV share and the global plant network.

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: Boyd's revenue is highly discretionary and exposed to the consumer cycle: gaming and entertainment spending tends to fall when households face inflation, job losses, or weaker confidence, which can pressure visitation, revenue, and margins quickly. For CYATY, customer concentration is shifting against CATL.

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 BYD if you believe its drivers more; CYATY 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 BYD and CYATY guides.

BYD. As of October 16, 2026, BYD trades near ~$69.80, about 9x analysts' 2027 EPS and ~6.9x EV/EBITDA, after a roughly 19% decline in 2026. The trailing P/E near 3x is misleading because the one-time FanDuel gain inflated reported 2025 earnings, so forward and EBITDA multiples give the cleaner read. Sixteen analysts carry a Buy consensus with a mean target near ~$94; Q3 results arrive October 22, 2026.

CYATY. Figures come from CATL's 2025 annual report and 2026 interim report, converted at roughly 7.1 yuan per dollar, with the trailing twelve months combining the two. Third-quarter 2026 results were due in late October, so these numbers predate that report; consensus looked for roughly RMB 183 billion of quarterly revenue versus RMB 104 billion a year earlier. The multiple has compressed because the share price fell about 45% from its spring high while profits kept rising. The CYATY price follows the Hong Kong shares, adjusted for the ADR ratio and the dollar exchange rate.

Headline figures (approximate, October 2026): BYD shows revenue (ttm) ~$4.1 billion (flat latest quarter), q2 2026 revenue / adjusted eps ~$1.03 billion / ~$1.93 vs ~$1.89 est., operating margin ~21%, p/e trailing / forward ~3.1x (distorted) / ~9.1x; CYATY shows revenue (ttm through june 2026) ~RMB 522B (~$73B), net profit (ttm through june 2026) ~RMB 85B (~$12B), h1 2026 revenue / profit growth +54.8% / +42.0% YoY, gross margin (h1 2026) 23.9% (down ~1.1 pts).

BYD and CYATY 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 BYD and CYATY exposure against your real portfolio. It is not an investment adviser.
