投資報酬率一直都是投資人最熱烈討論且比較的事，而營業員這項職業就像市場與投資人間的橋樑，建立兩者雙向溝通，三者缺一不可，近年來交易熱絡的股票往往受到證券交易所(以下簡稱交易所)的關注，自 2001 年 10 月 05 日開始交易所規定個股股票當其交易量、漲跌幅或是週轉率等等交易異常，會被交易所注意，注意之後會被列為注意股票，當該注意股票持續交易異常，交易所會列為處置股票，處置股票會以人工管制撮合終端機執行撮合作業時間，甚至情節嚴重者交易所還會要求投資人預收款券。 2017 年 4 月開始，行政院為活絡股票市場交易之熱絡，當沖證券交易稅由原本的千分之三降至千分之一點五(以下簡稱當沖降稅)，使市場成交量能擴大，投資人所投資之熱門股票，股票往往不再因為單一原因被注意，反而是因為股票週轉率異常而被交易所注意。本研究主要研究利用週轉率比較前一期之成長率來做投資組合，其與元大台灣卓越 50 基金(以下簡稱 0050 )做績效比較。本研究將用 2015 年至 2021 年七個年度來探討利用週轉率成長之股票前 5 名產生出投資組合做投資。實證研究結果顯示利用週轉率成長來做投資其績效表現有優於 0050 。
