This stock definitely has form for skyrocketing on good news, quickly settling back to about 1/2 the initial gain, then slowly returning to the original level. There are some differences to be aware of though:
1) That was gold and it was when gold was far off its highs. This is Zn, which is climbing.
2) There was no cash reserve so we knew that anything good would mean dilution to develop.

These factors were pretty heavy and the action was always short-lived. I've seen this one go to 350% in three days and be back at square one in three weeks.

Disclosure: I won't be selling into the pump and I'm not buying either at these prices.

But for those planning to trade on the action around the upcoming recommendations/announcements I would suggest that you consider trading in steps to average up just as you'd average down on a falling stock.
