If you're referring to the MVRBF shares, then there's an extra digit but i'll take a 5% jump. The impressive thing is the jump in volume.
Funny you should mention that. Mcbio and I wanted to pick MVRBF in the SI charity contest, but the esteemed administrator who runs the contest would not allow it because the trading volume was purportedly too low. As a result, mcbio and I were required to use MVIR-B.ST instead :- )
