What happens with me is, I buy things, they immediately dive, I wait around a while sitting at -20%, after a month or two I get tired of sitting on a particular investment that's always red so as soon as it's back above where I bought in, I sell and make 2-5% or whatever. Then I miss out on the huge gains that follow because I sold too soon. I'm sure all of this is avoidable, probably by only buying things when they're crashed. I generally end up in the green overall but it's a lot of wasted time sitting in things that are dipped.
