Tesla Stock Erases Yearly Gains as Rivian Charges Higher Amid Partnership Hype

U.S. equity markets saw a tale of two electric vehicle makers on Thursday, with industry leader Tesla Inc. (TSLA) sinking into negative territory for the year while rival Rivian Automotive (RIVN) extended its recent rally on renewed optimism.

Tesla Stumbles Under Weight of Multiple Headwinds

Tesla shares plummeted 6.6% on Thursday, marking their worst single-day percentage decline since July 24. The sell-off positioned the stock as the ninth-worst performer in the S&P 500 and the second-worst in the Nasdaq-100 for the session. Trading volume was heavy, ranking third-highest in the S&P 500 and second-highest in the Nasdaq-100.

The decline is part of a broader three-day slide during which Tesla has lost 9.7%, its worst three-day stretch since early June. The downturn has pushed the stock’s year-to-date performance into the red, down 0.5%, making it the only member of the so-called “Magnificent Seven” tech stocks in negative territory for 2025. This erases the gains sustained since September 12, when CEO Elon Musk purchased $1 billion worth of shares.

Several recent developments have contributed to the negative sentiment:

• Key Departures: Core employees managing the Cybertruck, Model 3, and Model Y programs announced their departures last weekend.
• Major Holder Trims Stake: Ark Investment Management, led by prominent Tesla bull Cathie Wood, reduced its holdings over recent sessions. A filing revealed that Ark’s flagship ETFs sold more than 70,000 Tesla shares on Wednesday.
• China Sales Slump: Data released this week showed Tesla sold just 667,861 China-made vehicles from January to October, a 10% year-over-year decline in the world’s largest EV market.
• Product Recall: On Thursday, Tesla announced a recall of approximately 10,500 residential energy products in the U.S. following 22 reports of overheating, including five mentioning fires. This follows a similar recall for Australian customers in September.

Rivian Rides Partnership Speculation and Price Target Boost

In stark contrast, Rivian’s stock continued its upward trajectory, climbing approximately 10.5% this week after surging over 12% last week.

The rally is fueled by two primary factors:

1. Upward Price Target Revision: D.A. Davidson hiked its price target on Rivian to $15 from $13, while maintaining a Neutral rating. This move was viewed positively by the market, especially after Goldman Sachs cut its price target last week following the company’s Q3 2025 results.
2. Expanded Partnership Potential: A Reuters report indicated that Volkswagen believes its partnership with Rivian could extend beyond their existing joint venture formed last year. Volkswagen sees potential for the co-developed technology to be integrated into its internal combustion engine vehicles. Carsten Helbing, co-CEO of the joint venture, endorsed the technology, stating, “The architecture is highly capable of also driving additional drivetrain configurations.”

Market Outlook

Tesla now faces significant challenges, including demand concerns, intense competition, and internal turbulence, causing its “Magnificent Seven” status to dim for now. Investors are closely watching for the company’s strategic response.

For Rivian, despite the recent share price appreciation, its deepening partnership with automotive giant Volkswagen and the potential for broader technological application present a compelling alternative for investors seeking exposure to the EV sector. While broader market fears persist regarding the expiration of EV tax credits, Rivian’s journey appears far from over.
