You are right regarding PK stocks. but where could you make 400% (or -99% lol) in a week ? SPZI isnt typical pinksheet stock. make DD and decide. I have nice posiotion in ALVR, but in TASE. im sure 2008 will be great year for ALVR. ( i hope they will win the contract of Australian government <A HREF="http://biz.yahoo.com/bw/070628/20070628005390.html?.v=1" target="_blank">http://biz.yahoo.com/bw/070628/20070628005390.html?.v=1</A> it could push the pps to the 20's ) elis
