For example, if an investor buys a 10 year bond and holds it for 1 year, the return is the same as buying a 1 year bond. The theory also assumes that risk premium does not exist and a security only earns its risk free rate
Liquidity premium theory states that risk premium increases with the maturity of a bond. The theory predicts that the yield curve is upward sloping due to liquidity premium
