When the fundamentals are very good, a dump can still happen.

That's pure technicals, the result of Wall Street bears' morning meeting. They can do it, and they have done it many times in history.
They can smash a perfectly rosy situation into something our own mothers wouldn't recognize.
With such a good opportunity, if I were them, I would do it too. I might even go all-in short. But I won't, for these reasons:
1) I'm a long-term holder.
2) I don't have the insider information that institutions have, so I don't know when to enter, especially when to exit.
