Been sitting on cash for the last year because people kept saying the bubble would burst. Is it too late for me to get in?

Back when the new admin was sworn in, the markets started going down, so I was scared to invest in the stock market. Then a few months later, stocks started going up, but people here said it was a fake rally and just market manipulation. I believed them and put all my savings into a savings account.

Then the AI boom started happening, and I wanted to get into stocks like Nvidia and AMD. Whenever I thought about buying them at different points throughout the past year, people here kept saying otherwise and that the AI bubble would burst any minute, so I kept my money in a savings account.

Now, it seems like the international situation is turning tides, and the stock market is up almost 2% today. I don’t even want to think about the money I could have made if I had just went with my gut and didn’t listen to people’s opinions who seemed so sure that the bubble would burst at any minute throughout the past year.

My question is, is it too late for me to invest in the stock market and AI stocks?
