nVIDIA's stock price

The price of nVIDIA's stock rose suprisingly high yesterday. It had risen after ChatGPT became poplular and AI became the focus of the market. Six month ago, it was difficult to believe that the price of the stock would rise. 

If I had bought a large amount of stock at that time, I could be rich now. Investing is very difficult. If you want to succed at it, you need research well and have enough confidence to believe that the stock will rise in the future.
