It is worth noting that the health care providers segment saw the busiest pace of deal-making in the last three quarters of 2013 with 284 total transactions, according to Modern Healthcare. Having a large weight to healthcare services providers is a favorable trait for any ETF in a year in which UnitedHealth (NYSE: UNH) is just one of five Dow stocks up at least 10%.

With 70.4% of its holdings considered small-cap growth names, it is not surprising that PSCH sports a biotech-esque P/E ratio of almost 31. That has not prevented investors from pouring almost $10.2 million of PSCH’s $195.4 million in assets under management into the ETF this year. PSCH holds 71 stocks and charges 0.71% per year.
