it has moved from around $5 to $5.50 on very very low volume. nobody wants to sell. I don't think i have owned a stock that is so tightly held. the buying from $5 to $5.50 in such quick time would normally have me wondering if a takeover was in the offing, but the volume is so low that I guess that is most likely not what is causing the jump. just a re-rate I guess, let's hope it keeps going; still on a very "undemanding PE".
