BioTime up big

I do not understand why BioTime is up again today and ACTC is down. BioTime needs 50 million dollars just to finish Phase 1 trials on Geron's [now BioTime's] acute spiral cord injuries. ACTC had great results at the half way mark, of there Phase 1/2 trials and they closed down.......BTX closed up 43 cents at $3.88 on outstanding volume of 581,946 shares, the three month avg. volume is 104,146 shares. .....ACTC was down under 9 cents at 0.082 on 46,081,681 shares wow! The three month avg is 8.3 million shares.....Geron was up 3 cents to close at $1.63 on only 470,695 shares. The three month avg. is 1.1 million shares. ....Good luck in this rigged casino,
