中文摘要
量化投資在近年來已經成為專業投資人士所青睞的投資策略之一,同時機器學習在金融領域中的應用也越來越普及,最近的研究表明,將機器學習模型與一般的量化投資所使用之數據相結合,可以有效地預測未來的股市,從而在交易市場中找到重要的特徵和機會。在量化投資的運用中,投資人會使用各種統計學和數學模型,以自動化及系統化的方法分析市場數據,藉此尋找獲利機會。與此同時,機器學習作為一種人工智能技術,可以更加精密地處理數據,並自動尋找數據中的規律和模式,從而提高投資策略的精準度和效率。本研究不僅將一般量化投資會使用到的資料結合機器學習模型,同時納入眾多由價格與成交量構成的技術分析指標,以及先前研究中所認為可以有效解釋股市大跌的特徵,包含負偏度(NCSKEW)和漲跌波動度(DUVOL),找出重要的特徵並將預測結果進行交易。經研究結果後發現:(一)在預測指數價格波動度後對交易方向的判斷精準度會較盲猜交易方向的決策優異。 (二)在預測指數價格波動度低的情況會展現出更好的準確度。 (三)對於訓練時間以及持倉時間應當適度平衡會優於其他較為極端的交易時間選擇。
Abstract
Quantitative investing has become one of the favored investment strategies among professional investors in recent years. At the same time, the use of machine learning in the financial field is becoming increasingly widespread. Recent studies have shown that combining machine learning models with the data used in typical quantitative investing can effectively predict the future stock market, thereby identifying important features and opportunities in the trading market. In the application of quantitative investing, investors use various statistical and mathematical models to analyze market data in an automated and systematic way to find profitable opportunities. Meanwhile, machine learning as an artificial intelligence technology can handle data more intelligently and automatically identify patterns and trends in data, thereby improving the precision and efficiency of investment strategies. This study not only combines the data used in typical quantitative investing with machine learning models but also incorporates numerous technical analysis indicators composed of price and volume, as well as features previously identified as effective in explaining major stock market downturns, including negative skewness (NCSKEW) and downside volatility (DUVOL). Important features are identified and trading is conducted based on the predictive results. The research findings reveal that (1) making trading decisions based on the predicted index price volatility is more accurate than blind guessing the trading direction; (2) better accuracy is exhibited in predicting index price volatility when it is low; and (3) a moderate balance between training time period and holding time is better than other more extreme trading time choices.
