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.

Shares of chipmaker Nvidia (NASDAQ: NVDA) have soared more than 2,400% in just the past five years. Can this still be an exceptional long-term investment, one that could potentially turn a $25,000 investment into more than $1 million over the long haul?

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.
