I understand Al's position about selling off and re-thinking when a stock drops 10% or whatever. Good to have a plan. Coming from a mutual fund background, I always looked at a drop as a buying opportunity. In the past, after DD'ing the heck out of some of my stocks, I held on, averaged down, (a cardinal sin, I hear) and wound up smellin like a rose and makin a ton. Breakwater warrants come to mind as about my best result. In at .35 then .25 then .15 then out around 1.40 in short order.
This has happened a few times and then all of sudden whoops. First, the market proves you have a brain with your success, then slaps you with an horrendous dead fish. (Westaim) I might be back to even when my estate gives it to my grandkids.
I like the idea that Al mentions wherein you get cost base to zero, toss em in a corner and wait. About 7 of my 20 stocks are these.
Because I am not a trader like Al, I see a drop, not as a loss, but as a gift. NOT, UC, ABI and FAN are working out well for now. Ergo, the market proves I have a brain, right up until it proves otherwise.
