I guess the cynical contrarian stance makes her a better trader than most around here.
It's likely. In one of her later posts, she wrote something to the effect that a good trader should be highly unpopular. Now the logical implication doesn't work in reverse of course, but she

I'd agree that a good trader would be unpopular around here. Also that the reverse isn't true. Otherwise the anti-Semite would be wealthy, rather than crying into his silver (shekels).
