本研究探討在全面開放現股當沖交易及調整上市及上櫃現股當沖交易稅率自千分之 3 降至千分之 1.5後，當沖交易已占每日交易量三成以上。此振興股市政策是創造政府稅收還是創造自己的財富? 樣本的取樣區間為2018年1月1日至2018年12月31日共12個月，並運用技術分析及籌碼分析進行實證。 實證結果發現，技術面及籌碼面用於現股當沖並無法得到任何有效的交易策略，並得證效率市場假說。 ;This study explores that when the full-opening of naked day trade and the adjustment of the over-the-counter and exchange market and the current naked day trade tax rate from 0.3% to 0.15%,the day trading has accounted for more than 30% of the daily trading volume. Is this revitalization of the stock market policy to create government revenue or create its own wealth? The sampling range of the sample is 12 months from January 1, 2018 to December 31, 2018 , and is empirically analyzed using technical analysis and chip analysis. The empirical results show that the technical and chip side are used for the naked day trading and can not get any effective trading strategy, and get the efficiency market hypothesis.
