Amplify ETFs recently launched an ETF allowing investors to place investments in the fastest growing public companies generating at least 70% of their revenue from online and virtual retail sales. The ETF was established to mimic the EQM Online Retail Index launched in December of 2015. Since launch, the index is slightly down and lagged the S&P 500.

Although one would think there isn't much diversity in the ETF, top 10 holdings are a mix of food service, gifting, marketplaces, travel, streaming video and specialty retail: GRUBHUB INC, ETSY INC, OVERSTOCK COM INC DEL, COPART INC, 1 800 FLOWERS COM, STAMPS COM INC, NETFLIX INC, FTD COS INC, BLUE NILE INC, PRICELINE GRP INC. I was a bit surprised to see Grubhub and Etsy as the top 2 holdings but when looking at all 45 holdings, all the majors you'd expect are there.

For those as bullish as I on the shift to online, IBUY looks like a solid pick if you'd prefer holding a mix of online players in place of individual picks.
