Is there any reason to buy a short bond fund (e.g. BND) when it yields less than a money market fund (e.g. SPAXX)?

L'auteur se demande pourquoi investir dans un fonds obligataire à court terme lorsque son rendement est inférieur à celui d'un fonds monétaire. Il souligne que les fonds obligataires peuvent perdre de la valeur malgré leur potentiel de gain en capital.

Why would you want to own a short duration bond fund when it yields less than money market fund? Yes, the bnd fund can go up in value, but it can also lose value. I thought you shouldn't expect price appreciation in a bond fund over time.
