HAP's top ten holdings account for 35% of the ETFs $107.3 million in total assets. HAP rose 25% in 2016 and 17% in 2017, and if you're interested in generating a better return than fixed-income investments would provide while guarding against inflation, HAP is a good option at an annual fee of 0.5%.
