Nvidia stock has been one of the biggest winners of the artificial intelligence (AI) revolution in the past couple of years, clocking remarkable gains of nearly 800% over the past two years on account of the red-hot demand for its data center graphics cards, but the past three months have been difficult for the chipmaker.

Investors could be encouraged by news from TSMC, which reported a surge in profit on strong demand for AI semiconductors.

It seems clear that 2024 was the year of artificial intelligence (AI) -- or was it? If you had invested in an AI-based exchange-traded fund (ETF) at the beginning of last year, the chance that you would have beaten the market wasn't great,

Will 2025 be the year that the king of the artificial intelligence (AI) sector is dethroned? To be sure, chipmaking giant Nvidia (NASDAQ: NVDA) isn't likely to take a trip to the dungeon. One obvious place to look would be among the companies Nvidia itself has invested in.
