I was going to start a thread in trading asking about your biggest loser that was a winner. I'll give my example.
Back after the tech wreck in early 2000's I had plenty of cash sitting around and took a flyer on 20,000 shares of AMZN pretty close to the low. The plan was to get out on some if it doubled and just hold the rest if it didn't go bust. I had read a story about Jeff Bezos and thought he could pull something off. I ended up holding past double and taking off 5000 shares to cover my entry cost including taxes on the trade. I don't remember the price exactly, but somewhere in the 30's I think. Well in 2011 we started with the oldest hitting college to be followed by 2 others over the next few years. I had sat through a lot of yoyo times with AMZN and thought it had run pretty far, and at the same time thought it might keep running. I ended up talking myself into getting out of the last 15000 around 230 in late 2011 or 2012, Fantastic profit, but holy shi-- did I fu-- up not holding onto at least some of it! I made great money, but missed a ton more.
