4 insiders bought a reasonable amount of shares as filed 1/4/13. Maybe an indication of goodness to come. I've been speculating on ACTC for a long time. I think 2013 will unlock a lot of value based on their successes. I would speculate that 0.25 pps, or $500M mkt cap is reasonable given the potential successes. Many studies have suggested that a $300M mkt cap for biotech is an indication of validity in the business model prior to FDA approvals. Since ACTC has orphan status, per se, there results will be watched closely. Good luck to all in this speculative investment.
