Risk Parity ? No Free Lunch

2013 was tough for risk parity. Many of the most popular funds such as Bridgewater, Salient and AQR were flat or down even as investors in the S&P 500 enjoyed a return of almost 30%.

What happened?

It might be helpful to look at interest rates, which have been trending downward since 1982.

Here’s a graph of the 10-Year Treasury Constant Maturity Rate:

As interest rates have gone down, Treasury bond prices, of course, have gone up, and it is plausible that interest rates were a factor in the strong performance of risk parity through the end of 2012. But in 2013, the trend showed signs of reversing, and that might have affected risk parity funds in two ways. First, higher rates mean lower bond prices. Second, higher rates mean higher financing costs. Since a levered bond portfolio is a key component of many risk parity funds, we might expect changes in rates and fund returns to move in opposite directions.

We saw this in 2013 for AQR’s fund:

and Salient’s:

Does 2013 mark the end of a phenomenal 30-year bond rally? Who knows? But a negative relationship between changes in interest rates and a strategy that levers a bond-heavy portfolio is not hard to understand.
