Artificial intelligence (AI) has probably been the hottest investment theme on the planet over the past year. You can go to Nvidia for GPUs and networking options, for example, or you can sign on for enterprise software to streamline the deployment of an entire AI platform.

Over the past year, a number of semiconductor stocks have witnessed meteoric gains thanks to ongoing euphoria surrounding artificial intelligence (AI). The share prices of Nvidia, Taiwan Semiconductor Manufacturing, and Broadcom have all risen approximately 80% over the last 12 months -- handily outperforming both the S&P 500 and Nasdaq Composite.

After the arrival of a less costly A.I. model from China, U.S. markets and academics are wrestling with the ultimate economic value of the technology.

Artificial intelligence (AI) investing is still one of the prevailing themes in the markets. Investors need to have some exposure to this trend, as it has the potential to be a generation-defining technology with a similar magnitude of impact as the internet.

Nvidia stock fell again as investors continue to react to the possibility that DeepSeek's new AI model means less need for advanced GPUs.
