Let's continue to ignore transaction fees and assume asan TCKR doesn't pay a dividend. You can "sell" the more expensive side of the equation and buy the cheaper side to make, for all intents and purposes, a risk-free profit. In practice, this means selling a put, shorting the stock, buying a call and buying the risk-free asset TIPSfor example.
