There's one final reason investors should consider buying Nvidia stock before 2025 -- its valuation -- but that requires some context.

This year has been one of milestones for top tech company Nvidia (NASDAQ: NVDA). Nvidia also won a spot among the elite, with an invitation to join the Dow Jones Industrial Average, and the stock became the best performer on the benchmark for the year.

Both stocks have had strong runs in 2024. Let's consider which semiconductor looks like the better buy heading into 2025.

In December 2023, I discussed the reasons shares of Nvidia could double in 2024. These included the robust demand for its graphics processing units (GPUs) for AI model training and inference, and the steps being taken by its manufacturing partner, Taiwan Semiconductor Manufacturing (NYSE: TSM), to ramp up supply.
