there is a zero-coupon bond.

its face value is $1000 and maturity 1year,

given that its market price is $800, need to find its expected return.

i want to know if this 'expected return' of zero-coupon bond is equal to the yield to maturity(ytm).

so my idea is that

ytm = (face value/ price of bond)^(1/maturity) - 1

= (1000/800)^1 - 1

= 0.25

= 25%

thus expected return is 25% * $800 = $200

is this correct?
