Define the time-0 log-moneyness of a call on stock $S$ with strike $K$ and expiry $T$ to be:


What does it mean for the strikes K to be at-the-log-moneyness?? I guessed this but i don't think it is right:

$$\log(K) = \log(S(0)\exp(rT)/K)$$


I would guess it means K=S(0)*exp(rt), so that log moneyness is zero.
