A one-year 10% Treasury bond with $100 par value pays coupons every quarter. An investor bought this bond at a yield of 4% pa and is planning to keep the bond until maturity, exactly one year from today. Coupon payments will be reinvested in the bond. The bond is free from default risk.

As of the settlement date, is it possible to calculate a minimum holding period return the investor could achieve? If yes, what is it (% pa)? If not, explain why.
