This study investigates the pricing efficiency of FTSE/ATHEX-20 index futures contracts and examines whether arbitrage profits exist in the Greek market. By comparing ex-post mispricing with round-trip total transaction costs faced by different groups of market participants, the empirical investigation suggests that profitable arbitrage opportunities are likely to be common in the Athens Exchange.

The current paper also documents and tests the factors that determine the occurrence and the magnitude of the arbitrage opportunities in the Greek futures market. The findings suggest that variables, such as futures maturity, dividends, volatility, liquidity and short-selling restrictions, explain effectively the cash-futures mispricing.
