The biotech sector is positioned in a breakout position in a vertical bull market! IBB and XBI are the two major biotech ETFs. IBB is weighted more towards mega cap biotechs, XBI is weighted more towards smaller biotechs that are the candidates having the potential to be acquired by the big ones. Both IBB and XBI have gone thru significant correction since the summer 2015 peak. XBI just broke out the 2015 peak and IBB has a little ways to take out the 2015 top.
