We are pleased to enclose an EDHEC-Risk Institute research article published in the Fall 2019 issue of the Journal of Fixed Income.

In this article "Defining and Exploiting Value in US Treasury Bonds", authors Riccardo Rebonato, Jean-Michel Maeso and Lionel Martellini, propose a definition of value in Treasury bonds that, they believe, is more satisfactory than definitions found in the recent literature, and that allows for statistically significant and economically relevant predictions of cross-sectional excess returns.

Their value pricing factor exploits the differences between the market and the theoretical values of Treasury bonds, where the theoretical value is assessed using an economically-justifiable Gaussian dynamic term structure model. Authors show that the profitability of the strategy they build using their value signal is statistically and economically significant and is closely linked to the Treasury market volatility.

They provide an explanation for this strong link using arguments similar to what can be found in the recent literature on liquidity in Treasuries; and they show that their value signal is not subsumed by the best-known return-predicting factors. With an eye to practical applications, they also present a long-only version of their strategy.
