"Most researchers in the United States, the United Kingdom and Canada such as Cross (1973), Gibbons & Hess (1981), Keim & Stambaugh(1984), Theobald and Price (1984), Jaffe & Westerfield (1985), Harris (1986), Smirlock & Starks (1986), Board and Sutcliffe (1988), Kohers and Kohers (1995), Tang and Kwok (1997) for six indices [Dow Jones Industrial Average Index (US),Financial Times Index (UK), Nikkei Average Index (Japan), Hang Seng Index (Hong Kong), FAZ General Index (Germany) and All Ordinary Index (Australia)] and many others have come to the conclusion that Mondays’ average returns are negative and Fridays’ are positive.
On the other hand, studies on the Spanish stock market have revealed that either there is no days of the week effect, [Santemases (1986), Pena (1995) and Gardeazabal and Regulez (2002)], or that on Mondays, the average returns are positive [Abascal (1993)].
Regarding the Greek stock market for the existence of days-of-week effect the results depend on the time period of researches: During the period 1985-1994, there were negative average returns on Tuesdays and positive during all the other days, with the highest being on Fridays, [Alexakis and Xanthakis (1995)]."
