“…Probably the most prominent of these effects are the Monday effect (see French, 1980;Pettengill, 2003;Keef et al, 2009), where Mondays' returns are much lower than other days of the week, the January effect (see Gultekin and Gultekin, 1983;Keim, 1983;Yao, 2012), where returns are much higher during the month of January than any in other month, and the turn-of-the-month effect (see Ariel, 1987;Kunkel et al, 2003), where returns at the end and at the beginning of a month tend to be higher than on other days. Recent research also considers Halloween effects (see Bouman and Jacobsen, 2002;Haggard and Witte, 2010) and even calendar phases exhibiting certain climate patterns (see Lucey, 2005, 2008).…”
