As stocks start to wobble after a nine-year bull market, one industry looks like it could break higher over the next few years.

This industry missed out on the spectacular bull market gains because of overbuilding, but last year's collapse in prices could bring a rebound off multi-decade lows. An ETF tracking the industry plunged 63% to its low last year from a high in 2011, but has since rebounded 20% as early evidence of a recovery becomes clear.
