anybody a clue why mos has been creeping up over last few days with bidders building and increased turn over..atm bidders are outnumbering offers...is it just a pump and dump to get the may options as close as possible to the money or something else driving sp higher?....unusual and nobody seems to be watching??...don't think they'll have the options in the money cause they'd have to pump sp close to 20 c which means a doubling of sp from here??..curious indeed and i certainly have no idea what's going on...cheers, anywhichway
