This paper investigates arbitrage opportunities and market efficiency by examining the put-call parity (hereafter PCP) in KOSPI 200 options market. The sample period is from January 2, 2001 to December 30, 2008. Interestingly, put premiums tend to be overvalued. Mispricing of OTM is larger than that of ITM or ATM. Overall, PCP does not hold in KOSPI 200 options market. It implies inefficiency of KOSPI 200 options market so that it is possible to make arbitrage profits by exploiting the violation of PCP. Finally, we regress the model to find an evidence on the relationship between the arbitrage profit and the underlying features such as maturity and moneyness. The maturity and moneyness positively affect the arbitrage profit in full and sub-sample periods.
