How do you hedge against an ETF (VOO) that’s been doing so well

I have made amazing returns with putting the majority of my money in VOO but I fear that it will take a downfall soon. How would you hedge your position against such a downfall. I have a 40%+ return and it's peaked so much. About 60% of my portfolio is in it. I was curious if I should move my money into anything that would be a hedge that there will be a downfall eventually?

Edit:
What I learned is to just stay in VOO and if something happens in the long run it’ll weather any potential storm.

I appreciate all the interesting strategies though! It will give me a lot to research regardless to understand some of the potential things you could do.
