# Hedge Pricing

In this section, we include the effect of trading fees on risk-neutral pricing, which we will denote with the variable

$c$

. using

$\phi_k$

to denote the proportion of the hedge purchased for a given strike in a given epoch, the return for "selling" it can be shown as $APR_k=12\times\left(\frac{1-c}{1-\phi_k}\right),$

and in order for a no-arbitrage environment, we must have the relation

$P_k=\frac{\phi_k}{1-c}.$

It should be noted that although the APR for selling a hedge may seem quite high, there is always a probability

$P_k$

of the seller's entire position being liquidated. Last modified 8mo ago
