Sell stocks and take profit or hold through up and down waves?

Wondering how investors handle their longer term held stocks. Do you sell occasionally and take profits if you feel the market is going to take a downturn or do you just hold through the waves. I have a lot of aapl and several other stocks and I’m thinking of selling a few hundred of each and re-purchasing during a dip.

I own appl at $70 (I sell CCs and puts to reduce my cost basis). When aapl has dipped to $120-$130 I tell myself I should have sold at $170 …taken profits and rebought. Since this sell will be long term capital gains the tax won’t be a big deal so not worried.

Am I the only investor that holds through the up and downs? Should I sell some and rebuy? Thank you in advance.
