SpaceX Cybertruck Purchase Sparks Strategic Synergy
Tesla's 4.31% intraday surge is directly tied to revelations that Elon Musk's SpaceX has purchased 1,000-2,000 Cybertrucks at $80K each, injecting $80M-$160M in revenue. This internal Musk ecosystem transaction transforms a commercial 'flop' into a strategic win, creating captive demand for Tesla's struggling Cybertruck division. The move also signals SpaceX's operational readiness for Starbase operations, with Cybertrucks serving as ground support vehicles. This inter-corporate synergy removes existential risk for Tesla's EV division while positioning SpaceX as a key growth catalyst ahead of its anticipated IPO.

EV Sector Mixed as Tesla Outpaces Peers
While Tesla surges, the broader EV sector shows mixed signals. General Motors (GM) rises 1.34% on improved Q4 production forecasts but lags behind TSLA's volatility. Rivian (RIVN) trades flat despite its Amazon partnership, while Lucid (LCID) gains 4% on production ramp rumors. The S&P 500 Auto Manufacturers index (+1.82%) trails Tesla's 4.31% move, highlighting the stock's unique exposure to Musk's ecosystem. This divergence suggests investors are pricing in SpaceX's potential IPO as a separate growth vector rather than viewing it as a Tesla satellite.

• Aggressive bulls should consider TSLA20251226C490 into a breakout above $490.86. The 50-delta call offers balanced leverage with high gamma to capitalize on continued momentum. For directional bets, TSLR/TSLG provide 8.5%+ daily leverage but require strict stop-loss discipline given Tesla's 411x P/E. Watch for a potential reversal if the 438.72 middle Bollinger Band fails to hold.

Backtest Tesla Stock Performance
The backtest of Tesla (TSLA) following a 4% intraday increase from 2022 to the present reveals poor performance. The strategy yielded a -63.14% return, underperforming the benchmark by 42.31%. With a maximum drawdown of 0.00% and a Sharpe ratio of -0.96, the strategy showed no risk mitigation, highlighting significant volatility and losses.

Tesla's Musk-Driven Rally: Hold for Breakout or Exit on Overbought Signals?
Tesla's 4.31% surge is fueled by strategic synergy with SpaceX, but the 411x P/E ratio suggests valuation risks. The 2025-12-26 options chain shows $26M+ in turnover, with 490/510 calls as top plays for continued momentum. Technicals favor holding for a breakout above $490.86 (intraday high) but warn of potential reversal if the 438.72 middle Bollinger Band breaks. Sector leader GM (+1.34%) underperforms, highlighting Tesla's unique exposure to Musk's ecosystem. Aggressive bulls should consider TSLA20251226C490 for leveraged exposure, while cautious investors may take profits near the 52W high of $495.28. Watch for regulatory filings on SpaceX's IPO timeline and Cybertruck production updates in early 2026.
