As most portfolio managers know, building a broadly diversified portfolio has one key building block. Low or negatively correlated assets. Ideally, if each of these building blocks has low correlation to the others, one or more will be falling in value while the others are going up in value. This ideal scenario lends itself to arbitrage opportunities and the ability to buy assets when the market has placed them ‘on-sale’. With that said, have you considered diversifying a portion of your portfolio into the Utilities sector? If you want low correlated assets in your portfolio, I would suggest considering the Utilities sector. The utilities sector has maintained a very low correlation to the U.S. Stock Market over the last 19 years, at just 0.39. I wrote more in depth about this low correlation phenomena right here: Which Equity Asset Class has the Lowest Correlation to the U.S. Stock Market?
