The case for indexing equity portfolios has been thoroughly established in the financial literature and, more importantly, in real-world results. The merits of indexing with respect to fixed income investing, by contrast, is more of a gray area. A recent study by AQR finds that bond fund managers aren’t generating Continue Reading

The financial crisis that ripped through the global economy in 2008-2009 ended more than a decade ago, but one of its most confounding offspring persists: low (and in some cases negative) interest rates.
