The number of investors betting that Nvidia, Broadcom, and Marvell Technology shares will fall has increased in December, following a year of massive gains for these semiconductor stocks. In 2024, shares of companies with heavy exposure to generative artificial intelligence saw huge increases as investors bet on the growth that the new and exciting tech could bring.

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

Complex data center workloads like training machine learning models and running artificial intelligence (AI) applications would take a very long time if powered only by central processing units (CPUs).

Broadcom (NASDAQ: AVGO) has been an outstanding investment over the past three years, as shares of the semiconductor giant have shot up an impressive 240% during this time and outpaced the 27% gains clocked by the PHLX Semiconductor Sector index over the same period.
