Quality may be the fuzziest factor you will find in the investing world. There is no one agreed-upon definition for it, nor is there clear consensus that it is a true stand-alone factor. What's more, it is missing the risk story, the basic economic intuition, and the readily discernible behavioral underpinnings that explain the existence and persistence of the value factor. Here, I'll address what quality is, why it may or may not yield superior risk-adjusted returns, and how investors can harness it with exchange-traded funds.
