Allied Irish Banks
I bought AIB for around $1.15 today. I really don't know whether or not it's going to go to 0, but I figure my odds of a triple are good enough to justify risking a strikeout.
This is in the same class of ACAS, but even riskier. If they do manage to return some of their monster cash flow to shareholders in a dividend, it will be a coup, driving the stock price to several times what it is now. But maybe they won't be able to.
