Well, another month goes into the history books. As you can see from the graphic I have put together (click on the graphic below to bring up a PDF version), it wasn’t a very good month. This most likely had to do with the looming debt ceiling deadline. July marked the third month in a row that the seven out of the ten indexes had a negative return. The last time that happened for the S&P 500 (the index that I have the most data for) was in 2008, when it happened twice.
Notice that I added a new column at the end for the weighted average return for all ten asset classes (assuming a ten percent stake in each asset class rebalanced monthly).
