在這篇論文裡，我們結合李承翰經由基因規劃法(gen expression programming)產生的交易訊號與江學者經由卷積神經網路(convolutional neural network)產生的投資組合，形成一個股票組合管理的投資方法。
江學者的方法主要是對比特幣進行投資，我們轉換江學者的投資物從比特幣到股票。當李承翰的方法產生一個買賣的交易訊號(買或賣)，我們會重新計算投資組合的權重。為了測試我們的方法，我們選擇存在於1995/1/5 到2017/12/29之間的213支股票，我們的訓練區間開始於1995/1/5，我們從2002/1/2開始交易到2017/12/29為止。
在我們的實驗裡有三種狀況的測試:利用100支股票的特徵去交易100支股票，利用213支股票的特徵去交易100支股票和利用213支股票的特徵去交易213支股票，這三個測試的年報酬率分別為25.00%、26.52%、27.32%。我們的方法比buy-and-hold 的方式好，100支股票使用buy-and-hold方式的年報酬率為12.36%，213支股票使用buy-and-hold方式的年報酬率為12.21%。我們的方法也比李承翰無投資組合管理的方法好，李承翰的方法100支股票的年報酬率為12.94%，213支股票的年報酬率為12.67%。

In this thesis, we combine the trading signals generated by the gen expression programming (GEP) method of Lee et al. and the portfolio generated by convolutional neural network (CNN) structure of Jiang et al. to form a stock investment method with portfolio management.
The method of Jiang et al. focuses on the investment of the cryptocurrency. We change the invested target of Jiang et al. from cryptocurrency to stocks. We recompute the weights of the portfolio when the method of Lee et al. generates a trading signal (buy or sell). To test our method, we choose 213 stocks which always exist during 1995/1/5 to 2017/12/29 on stock market in Taiwan. Our training period starts from 1995/1/5. We perform the trading from 2002/1/2 until 2017/12/29.
There are three cases in our experiments: Trading 100 stocks with the 100-stock features, trading 100 stocks with the 213-stock features, and trading 213 stocks with the 213-stock features. The annualized returns for the three cases are 25.00%, 26.52% and 27.32%, respectively. Our method is better than the buy-and-hold 12.36% for 100 stocks, and 12.21% for 213 stocks. Our method is also better than the method of Lee et al. without portfolio management 12.94% for 100 stocks, and 12.67% for 213 stocks.
