zeev , think this area on the BTK may present a hurdle finally ...550 currently & certainly is a "nice round number"...and @ R exactly here on the weekly chart ... <A HREF="http://stockcharts.com/def/servlet/SC.web?c=$BTK,uu[h,a]waclyyay[pb50!b200][vc60][iUc20!Lb14]&pr.." target="_new">http://stockcharts.com/def/servlet/SC.web?c=$BTK,uu[h,a]waclyyay[pb50!b200][vc60][iUc20!Lb14]&pr...</A>. you know the Bios are not my specialty , but may BIIB's eps may be a trigger... $57 seems to be presenting some probs here . I'd like to think short from here ...what feelings do you have to share ? They certainly all have achieved milestone valuations <g>
