QT Vascular also performed spectacularly but I have since sold it in June as it has gone beyond my "understanding" only to see it moved even higher.... (the sale was mentioned in my Facebook page).
Anyway it was a good return for me generating more than 35% in one month.
UMS holdings suffered from a double whammy in June where Applied Materials and also the CEO sold down their shares significantly. I haven't had time to analyze their moves but definitely it doesn't bode well for the Company when insiders are cashing out. I will decide if I want to sell the shares after my holidays :-P
