BTK could possibly be back-testing this old rising support/resistance line, currently at around 485 or so on the monthly chart: <A HREF="http://stockcharts.com/def/servlet/SC.web?c=$btk,uu[h,a]maclyyay[pb20!b50!b200!c13!c20!c50!i!d20,2!f][vc60][iub14!la12,26,9!lg!li10,10!lh5,5!lp14,3,3!ll14][J14042304,Y]&pref=G" target="_new">http://stockcharts.com/def/servlet/SC.web?c=$btk,uu[h,a]maclyyay[pb20!b50!b200!c13!c20!c50!i!d20,2!f...</A> If the SOX decline is stemmed here at 460-463, the BTK may take up the slack on a drop.
