Share price movement will equal expectation plus or minus...

Share price movement will equal expectation plus or minus however much better or worse the actuality is. Have you not noticed that's how it always works? Expectations are high, so good news is already priced in. The rumour has already been bought.

Holding right now seems very dangerous. I would be selling to those wanting to buy the rumour rather than risk being squashed by those selling the fact, or worse, finding the fact is less than the rumour. Having said that this stock probably has a slightly different following from most, so very short term it might be interesting. Time will tell, but with high expectations it's very dangerous to be holding in wait of news.
