Rydex Investments announced that shares of eight new leveraged and inverse exchange traded funds have begun trading on the American Stock Exchange. Select Sector ETFs "aim to offer investors magnified and inverse exposure" to the following Select Sector Indices: Energy, Financial, Technology, and Health Care. With more than $25 billion in benchmarked assets, Select Sectors represent the industry's largest and most liquid indices for sector investing, according to Rydex. On a daily basis, Select Sector ETFs seek to increase their benchmark exposures by 200%, and move in the opposite direction of their specific benchmarks, enabling investors to potentially profit during sector downturns.
