If the bond is held by the investor for one 12 months, this return as proven will precisely replicate the full return the bond holder obtained.
Utilizing this calculation, the bond’s present yield can solely be unfavourable if the investor obtained a unfavourable curiosity cost or if the bond had a market worth lower than zero. These two occasions are unlikely.
Calculation of yield to maturity

On this state of affairs, the bond chart will present that the bond could have a YTM of round 10.86%. If the bond holder had paid $ 1,200 for the bond, the YTM could be round -9.41%.
Nevertheless, a bond is not going to essentially have a unfavourable precise return just because the investor paid greater than its face worth.
