I was in ACTC for a couple of years.  For one year, the 52 week high was listed as .96, while it was trading .07 - .25 range.  Someone put in a market order which obviously was supposed to be for .096, and filled at .96.  Hope he didn't buy too many. LOL!

BTW, ACTC has some some issues at the moment.  I know we're waiting on 10K, but look at this form 4 for sales by CEO Gary Rabin.  http://www.secform4.com/filings/1140098/00010...001335.htm
