Revolution or pollution?
As they expand, providers are pushing into new areas—and, as BGI's Matt Scanlan puts it, "slicing the baloney thinner". BGI and Vanguard have begun offering fixed-income ETFs; BGI recently launched one that tracks junk bonds. In stocks, it is no longer enough to track the obvious indexes, such as the S&P 500 or the Nikkei. The ETF firms' eggheads have been working overtime to create customised baskets that approximate particular industries or asset classes. There are ETFs that track spin-offs, private equity, gold, vaccine stocks, intellectual property, nanotechnology, clean energy, and much more. Others are designed to allow intriguing bets on standard indexes: the ProShares UltraShort QQQ, for instance, is a "double inverse" play on the NASDAQ 100. Investors gain 2% when the index falls 1%, and vice versa.
