This study employs an event study using the market model with conditional heteroscedasticity to investigate the effects of media recommendations on the performance of electronics companies listed on the Taiwan Stock Market. The empirical results confirm that investors obtain significantly abnormal returns following different types of information around the announcement date when the news is released. These analytical results provide evidence that the stock market information is frequently leaked in advance of the announcement date and the investors generally adopt a conservative strategy following the release of information regarding a recommended stock.
