While these internet ETFs may be seen as a type of tech sector play, the two funds also include consumer discretionary exposure. Specifically, the internet ETFs include some e-commerce or online retail presence, so the funds may be susceptible to shifts in consumer spending and sentiment.

FDN includes a 70.0% tilt toward information tech names and a 22.1% position in consumer discretionary. Meanwhile, PNQI holds 57.8% in technology and 31.2% in consumer cyclical. [Which ETFs Will Best Capture 2015’s Holiday Shopping Trends?]
