my guess is that an announcment is due in two or three weeks. when the shares had been sitting in the thirties, a month or two back, there was a sudden spurt of buying on a friday. i thought that this might be a precurser to an announcement, two or three weeks down the track - this proved to be the case. i often notice this behaviour in stocks. the insiders who are privy to the information, talk, and those who care to listen, often jump in and buy.
just speculation on my part though
