Is now the time for fixed income investors to extend duration?

Neuberger Berman says clients consistently ask three questions: given today's yield curve, why shouldn't I simply roll T-bills? When should I add duration, and how much duration do I really need? Now is the time to invest in core bonds for investor seeking a higher yield and a multi-sector strategy makes the most sense. History suggests the window to add duration opens when the three month tenure inverts and when investors ask how much duration do they need, the answer is not much; because historically the 5-year outperforms the 10-year, the five-year is the sweet spot.
