The Influence of Date of Premiere on Stocks Rates of Return of Video Games Companies Listed on The Warsaw Stock Exchange

Summary/Abstract: The purpose of this article is to examine whether the selected events specific for video game companies have a statistically significant impact on stock rates of return. The analysed events which impact on stock rates of return were: setting a date of a video game premiere and postponement of a video game premiere. Moreover, the study tries to provide an answer to the question of whether the time of awaiting for a game premiere after its setting or postponement is related to stock prices. In order to collect and select the most numerous sample, an analysis of current reports of all fourteen video game companies listed on WSE Main Market and NewConnect Market in the period from January 4th, 2010 to July 31st, 2017 was carried out. The conducted study allowed for stating that the occurrence of the two event types mentioned does not have a statistically significant impact on stock rates of return. Only in the case of events classified as postponement of a video game premiere could a relation between the rate of return and the period of postponement be spotted. Such a relation is reflected as increased losses along with the postponement period extension.
