In actuality, American options are traded on an option-adjusted-spread (OAS) basis, where
OAS=Model Price-Market Price
For example, the value of the call bond is calculated according to our interest rate model is $100.3564, while the call bond is actually traded at $100.1 in the market. This produces OAS=0.2564>0. It seems as if the call bond has been undervalued and an arbitrage is warranted.
In this case, arbitrage means trading between the call bond and another portfolio, which replicates
the call bond.
