The world of exchange traded funds (ETFs) is nothing if not a hotbed of innovation. Rarely a week goes by without the announcement of a new type of ETF. We have noted this trend for some time with a degree of trepidation. Our wariness stems from the fact that the increasing complexity of ETFs could very well turn off individual investors seeking out a simple, index, cheap alternative to traditional mutual funds or broker managed accounts.
