As central banks conspire to drive down interest rates, both short-term and long-term, the question of valuation becomes an increasingly difficult one. One of the key inputs to valuation is known as the ‘risk-free rate’, and is generally based on long-term bond yields. As Quantitative Easing and negative interest rates send rates close to and beyond zero, analysts and fund managers must decide whether to adjust to lower-rates or maintain the status quo. In this Collection, we asked three contributors about how low interest rates have affected their valuations and investment decisions. Responses by Chris Prunty from Ausbil, Tim Kelley from Montgomery Investment Management, and Sean Fenton from Tribeca Investment Partners.
