Sounds to me like he can still go through quite a bit of antacid.
Now if he put 70% of his capital in these 3 stocks short, that means he could use the other 30% to use as a bit of hedging.
Maybe by hedging, the antacid raft ride might be a little easier to deal with.
As for myself - anytime that I start looking for reasons why I should stay in a losing postion, that means one thing and one thing only.
It's time for me to get out, dust myself off and look for a new opportunity. I don't have very much risk tolerance. I am very stingy with my cash. (maybe that's why I'm still here)
Seldom, do I find myself looking for reasons to stay in a losing postion. I'm so stingy, that I am usually out, long before this can happen. Either the trade goes my way soon, or I get out. I miss opportunities sometimes doing this, but I think that in the long-run I come out on top.
I trade under a "love to take my losses type of mindset". I have developed this over time and experience. The experience of having to look at my P&L and say to myself " a 100$ loss wasn't good enough for me, I had to wait around a hope until it became a 300$ loss, then it was good enough for me to get out" (yes I am a smalltime player) probably known to some as Joebob redneck piker...lol..... but regardless of size, I think the principle is the same.
My point is, that I tell myself to love to take the 100$ loss, don't wait to see if it can become a 300$ loss. I can always get back in the trade if I so desire.
