Insiders will begin to stick around, maybe, when the stock price begins a permanent move up. I know there's been some discussion about the negative effect a RS would have on current shareholders equity, but I observed another stock UNXL that R/S'd and after a momentary drop began a pretty big run up in share price. I sold when they R/S'd and that was a big mistake. I think its just a question of doing the R/S when the current trials and development of new potential stem cell therapies generate sufficient interest (demand) from institutional investors. It will dilute the interest of current shareholders but the institutional money will push the share price way high. I see insider selling even in companies with increasing share prices because that's just part of how insiders are compensated, it doesn't necessarily mean there's anything wrong with the company. As far as when is the right time to buy for current shareholders, I think anytime from now on is good because of the developments in the testing and the technology I believe its all uphill from here, excepting typical up and down days in the market this company is a first mover in a revolutionary medical field. Anybody that sells now is likley to get stung when this baby begins to grow. I'm thinking about selling some precious metals to buy more ACTC because I think I'll get a much higher return. This company is a potential microsoft.
