There is really only one time to consider going long as an investment, thats the morning of final results if the figures stack up. Until that point you are battling lack of figures from Zoo and those they have put out simply dont add up and point to significant full year losses and not a profit.
There may be positive news coverage on the iDVD market, there may be deals announced, there may be announcements by competitors, there may well be another cash call.....but bottom line is that they need to get their act together with the figures and show a sustainable path to profitability and growth.
