Over the past twelve months, Tesla’s stock has advanced approximately 14%, while the S&P 500 has gained about 20%, reflecting a significant relative underperformance. Looking back over five years, Tesla shares are up nearly 63%, compared with an 85% rise in the benchmark index. This persistent gap underscores investor concerns that enthusiasm for Tesla’s longer-term robotics and AI ambitions has failed to offset setbacks in its core electric-vehicle business.

In the fourth quarter of 2025, Tesla reported a 5.5% year-over-year drop in production and a 15.6% decline in deliveries, marking the second consecutive annual volume decrease for the company. Despite industry-wide EV growth, full-year unit sales fell short of expectations. Price cuts implemented late in 2025 provided only a modest lift to demand, while regulatory-credit revenue tumbled by 44% year over year and operating expenses surged by roughly 50%, squeezing gross margins and raising questions about near-term profitability.

Investors point to the absence of a mass-market model priced around $25,000 with comparable features to Tesla’s higher-priced cars as a key barrier to broader EV adoption. Tesla has also yet to deliver a genuine long-range variant; competitors such as Lucid have introduced vehicles exceeding 500 miles per charge, roughly double the industry average. Market watchers contend that bridging both the affordability gap and the range deficit will be essential if Tesla is to rekindle its earlier growth trajectory and outperform competing automakers.
