碩士 === 國立高雄科技大學 === 金融系 === 107 === The purpose of this study is to explore the correlation between news information and the Google Search Volume Index (SVI) and the trading activities of Taiwans financial and electronics industry listed companies. The use of media news as a proxy for information supply, and the number of times a Google search engine queries a companys stock name is used as a proxy variable for investors information needs. Investors do not have information about prophets like institutional investors, in order to reduce information asymmetry. Investors will conduct online search behavior before the stock trading behavior. After research and empirical evidence, the following results were obtained: 1.Through the Google search volume index and media news and the price limit, the turnover rate of the positive stocks will be higher than the turnover rate of the negative stocks. 2.The increase in the search volume index and media reports will increase the stock ups and downs. On the other hand, the correlation between the search index of the financial industry and the ups and downs is less obvious.
