Nvidia ( NVDA -3.00%) dominated much of the conversation among investors in 2024 as the stock marched 171% higher for the year. That was for good reason, as revenue and earnings exploded, with many big tech companies scrambling to acquire Nvidia's advanced chips for artificial intelligence (AI) data centers.

Nvidia Corp.’s $3 trillion run-up in market value in the two years since ChatGPT helped trigger an AI frenzy is bigger than any stock rally in history in such a short time span. But the landscape is now changing for the chipmaker.

Nvidia still carries the stock-boosting power, but its strength may be waning as some investors wonder how long it will last. According to a recent Bloomberg report, Nvidia founder Jensen Huang’s praise of Samsung Electronics memory chip capabilities last Wednesday prompted a 3% jump in the company’s shares.
