Nvidia is currently about 13% of my total portfolio. It feels a little heavy since a good chunk is based on this one company, albeit a world class one. Should I sell some off?

Currently, about 70% of my portfolio is VTI and other S&P500 index funds. Thats my core and prefer to keep index funds the foundation of my portfolio so that I don’t have to constantly be studying my portfolio and the different stocks and companies. I like to be a little more passive and hands off on my investments so I’m not constantly worried about what everything is doing.

Any index mostly investors here can put some insight on if Nvidia is too much in my portfolio?
