I agree. I still beat myself up for not selling everything in December. My portfolio was worth $100k - the profits would have been huge.
Now would have been a perfect time to buy in again.
But I was stupid enough not to sell a thing, and now my portfolio is worth only 1/6th or so.
But I guess there is no use crying over spilled lik. Only lessons to learn. When the bull run goes as high again, there won't be a doubt in.my mind about selling and cashing in at least part of my profits...
