Citi analyst Andrew Kaplowitz expects Quanta Services' 2018 to bring a continuation of rising backlog and revenue in both its Electric Power and Oil and Gas units as well as gradual normalization of margin toward margin targets. Further, the company should be a prime beneficiary of U.S. tax reform, Kaplowitz tells investors in a research note. Quanta had a good year in 2017, and 2018 is "poised to be better, and maybe a lot better," the analyst contends. As such, he thinks Quanta Services is a "holiday treat for savvy investors." Kaplowitz has a Buy rating on the shares with a $47 price target.
