Fund managers may be serious, all-business sorts, but there is still opportunity for some creativity when naming their offerings. In March, Pimco's Enhanced Short Maturity Fund became the very first actively managed ETF to exceed $1 billion in assets under management. The ticker, ( MINT), might make you think of printing money, which was the intent for the near-cash, capital preservation strategy of its investments in money markets, longer maturity bonds and investment-grade fixed income securities. SPDR Barclays Capital 1-3 Month T-Bill ETF went with the simple ( BIL) while WisdomTree International Hedged Equity Fund, a "fund of funds," sounds out its strategy as ( HEDJ). U.S. Global Investors, an investment management firm that includes emerging markets among its focus areas, has the ticker ( GROW), exactly what one might hope those foreign investments will do for the mutual funds it manages.
