He has a point. Futures-based commodity ETFs also employ a potentially dangerous level of complexity, while ETNs expose investors to risk they don't always understand. Older ProShares leveraged funds such as UltraShort Real Estate (SRS), UltraShort Financials (SKF) and Ultra Financials (UYG - Get Report) employed a somewhat simpler methodology than their contemporary peers. As it is impossible to generalize about the nature of all ETFs, it is also impossible to generalize about the nature of leveraged ETFs.
Leveraged ETFs can be useful tools for professional traders looking to hedge positions on an intraday basis. These funds have been marketed to the public, however, and until recently the image has been somewhat deceptive.
FINRA posted a warning on its Web site earlier this month about leveraged ETF products, and increased regulatory scrutiny is likely coming down the line. No one would argue that matches and blowtorches are the same thing -- but there is a place for both in harnessing the power of fire. There is a place for both leveraged and index ETFs, but investors must understand which ones they need.
