- Meta (META) shares closed 10% higher the day after it announced results, their biggest intraday jump since July 31, after the Facebook parent gave a revenue outlook that was much stronger than expected, which helped offset the impact of higher AI-related spending. The social networking giant topped projections for holiday quarter revenue and gave a strong forecast for the current period during its earnings report Wednesday. Improvements in its online advertising business are making it possible for Meta to spend hundreds of billions of dollars over the next few years on AI infrastructure. Meta’s shares jumped more than 11% in extended trading.

- Royal Caribbean Group (RCL) soared 17%. While adjusted earnings and revenue for the fourth quarter were in line with expectations, the cruise operator's 2026 earnings guidance blew past forecasts.

- Microsoft (MSFT) plunged the most in almost six years after reporting record spending and slowing cloud sales growth, fueling investor concerns that it could take longer than expected for the company’s AI investments to pay off. The shares sank by as much as 11% to $429.24, for the biggest intraday slide since March 2020.
