From the link:
But I’m here to confess to an obvious mistake and to sing a trader’s lament.
I sold half the position in this stock when it was up a “mere” 16 percent on a sell signal that…uh…didn’t exist. At the time, I must have thought it could go no higher although I’ve often said that this is the stock to buy among the golds because it has been “wild and crazy” enough to double. I must have thought the doji the day before I sold was a sign of the indecision that would lead to a sell down although the stock was up the day after the doji when I sold that half. I must have thought…
Clearly now, I think I was thinking too much. Which is one of biggest sins a technical trader can make. Better to not think at all.
