Realize gains and play safe, or just forget about it and come back in 10 years?

I’ve got a bunch of big names that have done well in the last couple months, Stocks like apple, Microsoft, nvidia, meta, and google. should I take the W and put it into VTI/VFV, or just pretend it didn’t happen and come back to the stocks in 10 years. Nothing crazy, just a few houndred bucks between the bunch of ‘em, but I’d just DCA back into an ETF.

I’m young and don’t care about making money for the next 10 years.
