Looking back for 5 years what sector shows double performance of S & P 500? How this sector feels recently?

Sees below since 2012 the Chart reflects in Bio-Tech ETF XBI that within the last 5 years of S & P it was very good as growth constitutes up to 70%. For the same period of time growth of XBI constitutes up to 160%, receiving more than 100% more, than other markets.
Exerted Bio-Tech impact on the broad markets as it didn’t decrease from summer of 2015 to February, 2016 of S & P made too. After Bio-Tech turned out above, 1 a year ago, the market in general followed forward though the broad market lagged behind this leader sector from minima.
Now XBI works at break in the annual drawing a long pennant, to top. If the history repeats, and this leading sector will go forward, then will have a great influence on the broad markets. The risk on stock exchange trading wants to see XBI to clear maxima of the end of 2015 (where in the upper part of the drawing of a pennant of the beginnings). This level joins the game as the test of resistance.
