Nvidia stock dropped 17% on Monday, Jan. 27 in an unprecedented bloodbath in the AI sector. In fact, it was the worst single-day dollar-value loss for a single stock in history, as Nvidia gave up roughly $600 billion in market cap.

Nvidia (NVDA) is a world leader in artificial intelligence (AI), gaming, visualization technology, and accelerated computing. The company is well known for making graphics processing units (GPUs) for the PC gaming market and high-performance computing.

Nvidia's strong financials and revenue growth, the popularity of its products, and the diverse range of applications for its chips put the company in a position to prosper for years to come, making its stock an excellent long-term AI investment. And now is a good time to buy shares.
