Stock Market Summary – December 16, 2025

Tesla shares achieved a new record high, climbing to $489.48 being driven by CEO Elon Musk’s mention of testing autonomous vehicles in Austin, Texas. The surge in Tesla’s shares led to a market capitalization of $1.63 trillion, making it the seventh most valuable publicly traded company. However, the company sales in EVs still remain weak. For the first quarter, Tesla reported a 13% decrease in deliveries and a 20% decrease in automotive revenue. The decreased sales are due to a consumer backlash against Musk’s political endorsements and his work with former President Trump.

Capital One had a favorable rally today, receiving a positive price target bump from both Bank of America and Morgan Stanley with new targets at $268 and $280 respectively. Both firm’s research focussed on Capital One’s steady credit metrics making it an attractive investment.

Drastic movements in the market are indicated for Southwest as stocks climbed over 2% after Barclays gave the company an overweight rating. On the other hand, energy companies like Halliburton and APA suffered losses with West Texas’ crude oil dropping to 2021 prices. Pfizer also had a negative day with shares dipping 4% due to disappointing 2026 profit forecast.
