§Winston Score History

The full picture

Tesla makes electric cars, trucks, and SUVs that run entirely on battery power instead of gasoline. Its main products include the Model 3, Model Y, Model S, Model X, and the newer Cybertruck. Tesla also sells solar panels, home battery systems called Powerwalls, and energy storage products for businesses and utilities.

Tesla earns most of its revenue by selling vehicles directly to consumers, cutting out traditional car dealerships. It operates in North America, Europe, and China, with major factories in California, Texas, Nevada, Germany, and Shanghai. Tesla's main competitive advantages are its charging network, software capabilities, and brand loyalty among EV buyers. However, with an operating margin of just 4.2% and growing competition from both legacy automakers and Chinese EV brands like BYD, the company faces real pressure on pricing and profitability. Its ability to scale its autonomous driving technology, called Full Self-Driving, is widely seen as the biggest factor that could either strengthen or strain the business going forward.

Revenue accelerating

Tesla grew revenue 26% year-over-year and the growth rate is speeding up. That's the kind of momentum growth investors look for — the question is whether margins can follow.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
