The kind of pattern that I've been shorting like crazy lately is the HADWAMR. (huge-ass dome with a massive retracement), which is pronounced "had-wammer". They've been turning up everywhere.
It takes these things a while to cook, but sometimes they blow right up. AVY is today's example, which is down double digits of percent, whereas HTCH, another short of mine, was an example from earlier this week. I {heart} this pattern.
