本研究以 8 種單因子與 4 種雙因子組合搭配各種策略組合進行實驗，主要交易策略
共有買入持有與動態換股 2 種策略，另外動態換股包含其他設定，例如最佳化參數窗格

combinations using various methods, but few studies continue to explore the verification of
multi-factor models combined with technical analysis strategies, and how to build these
automated backtesting and verification platforms. In this regard, this research refers to the
concept of similar experimental design proposed by 謝昀峻 (2018). Based on this, it adds a
multi-factor model combined with a technical analysis strategy dynamic exchange stock
strategy. At the same time, it improves the ability to dynamically allocate capital weights
according to conditions, and use walk forward analysis which is a portfolio optimization method,
proposed by Pardo (2011) to design system process, so let it can dynamically verify the stability
of the strategy. However, its system architecture and process design have various limitations
and cannot be compatible with the above requirements. Therefore, this research uses Python to
develop an automated backtest and verification platform with the above functions. In addition,
because the system process design of the walk forward analysis requires more computing
resources, the system architecture is designed with reference to the multi-node detection task
distributed algorithm used in the research of 林泓志 (2020). It uses multiple hosts to perform
simultaneous operations to share the computational load.
This study uses 8 single-factor and 4 dual-factor combinations with various strategy
combinations to conduct experiments. The main trading strategies include two strategies: buy and-hold and dynamic stock exchange. In addition, dynamic stock exchange strategies
includes other settings, such as in the optimization parameter window configuration, there are
fixed parameters, anchored, and non-anchored; There are equal capital weight and maximum
capital utilization methods in the capital weight distribution method. Besides, we will
experiment with various combinations to select candidate stocks in different groups and the
difference in holding different maximum number of shares. Finally, the performance will be
presented in a variety of visual charts to analyze the performance of the strategy from different
perspectives. |
