I did try to average down, and every time it went down more, making it seem like pouring money in a toilet. Some of my shares sit in an account I don't touch and I see the depreciated value daily, some in another account I've finally decided to flip as often as I think I can make a few percent and have been able to nearly double my share count in that account. Tenkay once said "I make my money when I buy, not when I sell.", or something like that. That has really helped me. Now I set my low price and yet, and verb is good at delivering those prices given a little time.
It seems to me that averaging down is little more than trying to offset a bad decision with a hopeful decision.
