U.S. Stock ETFs 'Decouple' From Foreign Stock ETFs

Prior to the 2007-2009 financial meltdown in the U.S., risk-takers thoroughly embraced the idea that emerging markets would regularly trounce the developed economies. At times, this simply meant that emerging market stocks would outperform on the upside. At other times, this referred to the ability of “emergers” to hold on to gains… even if U.S. stocks were faltering.

The investing idea that one region’s equity markets could move independently from another’s market had been dubbed, “decoupling.” In fact, the term received so much attention, it has been used to described unanticipated moves between other types of risk assets. For example, high yield bonds are supposed to behave more like stocks. At the start of 2013, however, rate sensitivity had caused the class to dip with investment grade bonds, and “decouple” from the rising stock market.

As the media celebrate record highs for the Dow Jones Industrials, you won’t find much about the decoupling that has occurred in 2013. Vanguard Value (VTV) has jumped roughly 7.5%. In complete contrast, Vanguard Europe (VGK) is flat and Vanguard Emerging Markets (VWO) is down -4%.
