sudden jump

Hi

I noticed TSM has jumped pretty suddenyl from 20c to 23.5c. Been holding since this was 35c (thanks Fat Prophets for the recommendation, but I have myself to thank for ignoring my stop). Does anyone have any thoughts as to why the sudden jump?

I notice technically that some prettylarge volumes were traded on May 24th and 25th, and particularly on the 25th there was 4.5M shares traded on the bounce from the previous day's fall - just wondering whether that may have been "smart money" buying in and now marking the price up?

Cheers, Sharks.
