Abstract:

In this paper, we have examined whether it is possible to make arbitrage profits on OMXS30 index options. We used the Put-call parity formula and performed a regression analysis to test our hypothesis. We find that it is impossible for a private investor to make new additional arbitrage profits on OMXS30 index options. Large institutions may find arbitrage opportunities, even though it is not certain that they will always make a profit from it. Thus our conclusions are that the OMXS30 is a highly efficient market, and will become even more efficient in the future as computerized trading develops.
