FDN “has surged 189% over the past five years, through Tuesday. That far outpaces the 122% increase in the PowerShares QQQ Trust Series ETF, the biggest tech-focused fund, as well as the 79% gain enjoyed by the benchmark S&P 500 over the same period,” according to Business Insider. “It already appears as if traders have caught on to some degree, with FDN swelling in size to become the third-largest tech ETF.”

FDN’s primary rival is the PowerShares NASDAQ Internet Portfolio (NasdaqGS:PNQI). PNQI tracks the largest and most liquid U.S.-listed companies engaged in internet-related businesses and employs a modified market cap-weighted indexing methodology based on the market cap ranking of the underling idnex securities.

The new, aforementioned FNG could give FDN a run for its money as well.

Unlike traditional beta-index strategies, “actively managed aspect of FNG allows for evolution and relevance, as opposed to the constraints and staleness that can follow index-based ETFs,” according to AdvisorShares.
