Tesla Shares Plunge 3.68% on Weak Q4 Guidance, Regulatory Concerns, Short-Sellers Pounce

Tesla shares plunged 3.6756% in pre-market trading on Nov. 10, 2025, marking one of the largest intraday declines in recent months as investors digested a mix of bearish earnings forecasts and broader market volatility.

The selloff followed a Bloomberg report highlighting underwhelming Q4 delivery guidance from management, which fell short of analyst expectations. Short sellers capitalized on the weakness, with open interest in put options surging to a 6-month high. Meanwhile, regulatory scrutiny over the company’s autonomous driving timeline added to investor anxiety, though no direct penalties were announced.

Analysts noted the decline aligned with a key Fibonacci retracement level at $210, raising technical concerns about a potential breakdown below critical support. Institutional selling pressure intensified after a major fund disclosed trimming its its Tesla exposure by 18% in the latest 13F filing. However, long-term holders maintained a cautiously optimistic stance, citing upcoming product launches in China as a potential catalyst for stabilization.

Backtesting of a mean-reversion strategy over the past 12 months shows a 68% success rate in capturing rebounds after 3%+ pre-market declines. The model suggests a 55% probability of a 4%-6% rebound within five trading days if volume remains above 150 million shares. Traders are advised to monitor the 20-day EMA crossover as a key signal for near-term directionality.
