Richard Shaw (QVM Group) submits: MLPs have generated higher yields than bonds or stocks over the past ten years, but have exhibited higher volatility than bonds, more like the volatility of stocks (see Part 2). However, the correlation of returns between stocks and MLPs over the past several years is only moderate, making them more useful in an asset allocation / rebalancing program than some other securities with higher correlation to stocks. As stocks and bonds have tended to have a negative correlation in recent years, MLPs and bonds have also had negative correlation. This table of correlations between stocks (represented the S&P 500 index fund, VFINX), bonds (represented by the Barclay's Aggregate Bond index fund, VBMFX), and the ten largest MLP's in the Alerian MLP index, shows the correlation for 1 year, 3 years, and from the stock market peak to trough (10/2007 to 03/2009), and from the stock market trough to now (03/2009 to 07/2010). In each case the correlation between stocks and MLPs is only moderate, and the correlation between bonds and MLPs is negative, as it is between stocks and bonds.Complete Story »
