iShares MSCI USA Momentum Index Fund (NYSEArca: MTUM)
AUM: $184.8 Million
Comment: MTUM is one of the three iShares ETFs developed at the request of the Arizona State Retirement System, which seeded $100 million to each of the three funds. It is always nice for an ETF to start out with $100 million, but to MTUM’s credit, it has added almost 85% since its April debut. Like QUAL, MTUM charges just 0.15% per year.
