The Most (Slightly) Favorable Time of the (Bond) Year

  • SumoMe

When it comes to investing, opportunity is wherever you find it.  And one of the keys to investing success is finding an “edge”, however slight.  So let’s talk about a slight edge in the bond market.

The Period

Let’s look at the performance of long-tern treasuries only during the months of May through August compared to all 4-month periods.

For testing purposes we will use the Bloomberg Barclays Treasury Long Index monthly total return data starting in 1973.

Figure 1 displays:

*Average 4 month return

*Median 4-month return

*Standard Deviation of 4-month returns

*Average 4-month return divided by standard deviation of 4-month returns (i.e., reward divided by volatility)

*Worst 4-month performance

*% of times the 4-month period showed a gain

As you can see, the May through August period has – on average – outperformed the “average” of all 4-months periods
