The anomalies that aren't there: The weekend, January and pre-holiday effects on the all gold index on the Johannesburg Stock Exchange 1987-1997
This paper investigates the existence of the Weekend, January and Pre-Holiday effects in the All Gold Index on the Johannesburg Stock Exchange over an 11- year period; 5 January 1987 through 15 May 1997, and for three sub-samples of equal length. These results are in severe contrast to the overwhelming international evidence documented for the stock markets of many other countries, be they developed or emerging markets: there appears to be no Weekend, January or Pre-Holiday effects, present in the All Gold Index.
