Ok This guy bought 670 thousand plus shares because he or she new a pr was coming out on or there about may 18 that would say Mr. Rabin will be providing information on ACTC's ongoing human clinical trials in the U.S. and Great Britain. { I did not know Rabin was going to discuss results of clinical trials on May 10, did anyone else?} Even I would say a PR like that would be good for a 2-3 cent raise and if i was privy to info before the general public got it I would say it would be a sure bet to make some serious coin and would go all in. Is that Legal ???
