You have explained well how you are determining the point to sell. But how do you determine that "the dip" is now?

Anytime it dips due to some announcement, I buy (usually big cap stuff like AMZN, or index like VOO). Then I sell when the price goes back to what it was prior to announcement

Obvious problem - stock market could keep going down. Obvious improvement - stop limit sell orders. Obvious flaw in the story - many common stocks like Google have doubled in the past year.

So if you had a pension mostly in all world indexed funds, you'd switch them over to "boring" investments like cash.

Interesting. Do you buy indexes, or ?

Mostly VOO and others. But I do buy big cap stock as well.
