Auto Stocks Are Cheap: What the Renault, Stellantis, Tesla and BYD Valuation Gap Really Shows

Why European Auto Shares Are Punished While US Names Rally

European carmakers have become some of the stock market's clearest laggards. BMW fell 35% between January and mid-June 2026, the worst performance in the DAX 40, while Mercedes lost 25% over the same period. In Paris, Stellantis suffered the biggest CAC 40 decline of 2025, and Renault has lost about three-quarters of its value over ten years despite strong gains in 2023 and 2024. Antoine Fraysse-Soulier, market analyst at eToro, attributes the pressure to rising costs, regulatory uncertainty, Chinese competition and a destructive price war.

The picture is very different in the United States. Tesla has risen about 50% since 2024, and GM has doubled over the same period. The Chinese market, by contrast, has weakened over the past three years. The analyst sees the broader industry in the middle of a multi-decade transition from combustion engines to electric vehicles, with 20 million electric and plug-in hybrid vehicles sold in 2025 out of an annual global market of 91 million vehicles.

That shift is reflected in valuation spreads. BYD is valued at roughly $100 billion on the market, compared with about $1.4 trillion for Tesla. Fraysse-Soulier says that gap could eventually become an interesting long-term entry point, especially as BYD removes price barriers with models such as the Dolphin offered at 23,990 euros.

European manufacturers, however, face much thinner room for error. BMW cut its 2026 margin guidance to between 0% and 2% in mid-June, while emissions rules and purchase subsidies remain unclear for consumers. The analyst still sees positive catalysts in software and batteries: CATL leads the battery market, Tesla carries a software premium for robotaxis and autonomous driving, and suppliers such as Nvidia, Qualcomm and Valeo are direct or indirect beneficiaries of electrification.

Where Renault, Stellantis, Tesla and BYD Now Stand

European Valuations Look Cheap Because Profitability Is the Real Question

Stellantis trades at two to three times earnings, but the market is not simply ignoring the sector. BMW's cut to a 0-2% margin range for 2026 shows that the price war is already reducing actual profitability, not just sentiment. A low multiple can persist if margins keep falling; the cheap valuation is an opportunity only if European manufacturers can stabilise pricing and defend profits.

The Tesla-BYD Gap Reflects a Software Premium, Not Just Car Sales

BYD's $100 billion valuation against Tesla's $1.4 trillion looks extreme, but the gap has a logic. Tesla's stock price includes what Fraysse-Soulier calls an artificial intelligence premium for robotaxis, the Optimus humanoid robot and full self-driving, none of which is monetised yet. BYD is priced more like a hardware company, even as it pressures Western rivals with aggressive pricing such as the 23,990-euro Dolphin. Whether that gap closes depends on whether Tesla's software bets justify their premium or BYD's vehicle scale converts into sustainable profits.

Batteries and Chips Are Where the Industry's Value Is Moving

The more attractive economics may lie outside traditional carmaking. CATL holds 39% of the battery market and is valued at $280 billion, nearly three times BYD's market value. Nvidia and Qualcomm are positioned as beneficiaries of electrification and digital cockpits, while Stellantis announced in May 2026 that it would adopt Qualcomm's Snapdragon Digital Chassis for future architectures. Valeo, which supplies cameras, radars and other hardware, is also named as a winner. The analyst's framing suggests the software-defined vehicle is shifting value away from low-margin assembly toward suppliers that control batteries, chips and digital systems.

Watchpoints for Anyone Eyeing Auto Equities

For investors and professionals evaluating the sector, the analyst's framework points to several specific triggers rather than a blanket buy case.

• Watch margin guidance, not sales volume. BMW has already lowered its 2026 margin range to 0-2%. If European OEMs cannot defend pricing, their low valuations may persist.
• Monitor interest rates as a demand signal. Higher rates reduce household purchasing power and discourage vehicle purchases, according to the analyst.
• Track the price war's profit effect. The central question is no longer who sells the most cars but who actually makes money selling them. BYD's 23,990-euro Dolphin directly pressures Western pricing.
• Separate Tesla's AI premium from automotive earnings. Tesla's valuation includes robotaxis, Optimus and full self-driving that are not yet monetised. Any reassessment of those bets would change the stock's case.
• Look at battery and chip suppliers as a different exposure. CATL has 39% battery market share, and Nvidia, Qualcomm and Valeo are named as direct or indirect beneficiaries of electrification.
• Watch regulatory signals. Changing emissions standards and unclear purchase subsidies are cited as a near-term barrier for European consumers and manufacturers.
