特斯拉（TSLA）：一家或将陷入衰退的成长型企业

Core Viewpoint - Tesla's stock price has remained stagnant since the downgrade to "sell" in October 2025, with recent quarterly earnings and delivery reports reinforcing bearish sentiments, presenting a rare exit opportunity for investors [1]. Energy Storage Business - Tesla's energy storage capacity reached a record high of 14.2 GWh in Q4 2025, with a total annual installation of 46.7 GWh, indicating strong expansion [4]. - However, the year-on-year growth rate for energy storage installations has significantly declined to 49% in 2025, down from 114% in 2024 and 126% in 2023, with projections suggesting a further slowdown to 26% by 2029 [4]. - Revenue per GWh from energy storage has halved from nearly $700 million in 2020-2021 to $276 million in Q3 2025, indicating a continuous decline [4]. Automotive Business - Tesla's automotive deliveries fell by 16% year-on-year in Q4 2025, marking the worst quarterly performance in the company's history, with a total annual decline of 9% [7]. - The average selling price of Tesla vehicles dropped below $40,000 as of Q3 2025, raising doubts about the feasibility of reaching a projected annual delivery of 3 million vehicles by 2029, which would only represent a 28% growth from 2025 [8]. - In the Chinese market, Tesla's sales stagnated while competitors like Xiaomi saw significant growth, and in Europe, Tesla's new car registrations plummeted by up to 71% in various countries, leading to an estimated 25% decline in overall registrations for 2025 [9][10]. Emerging Business Risks - The anticipated sales of Tesla's humanoid robot, Optimus, are already factored into current valuations, with market expectations suggesting a potential revenue of $22.5 billion by 2027 [11]. - Current valuations are deemed excessively high, with a forward P/E ratio of 147, indicating a disconnect from fundamental performance [11]. - The company's reputation has been adversely affected by the founder's political stance, leading to a significant loss of consumer trust and core personnel risk, which could further undermine market competitiveness [13]. Conclusion - Tesla is no longer viewed as a high-growth company but rather as one facing significant challenges and potential decline, suggesting that now may be the last opportunity for investors to exit [14].
