中文摘要
論文中,我們針對共同基金提出了兩個以基因規劃法為基礎以改進交易策略的模型。
這兩個交易模型可幫助投資人增加投資報酬率並減少投資風險。第一個交易模型使用
索丁諾比率(Sortino ratio)來選取基金,並且平均分配資金至被選取的基金以增加
投資報酬率,此模型在實驗中有最好的年化報酬率。第二個交易模型同樣使用索丁諾比
率來選取基金,但改以平均數變異數模型為基礎,分配資金至被選取的基金以降低風險。
最重要的是我們的交易模型使用了基因規劃法建構交易策略,基因規劃法所得出的交易
策略相當適合用在瞬息萬變的交易市場當中,以增加投資報酬率。
為了驗證交易模型,從1999年1月至2009年12月(共11年),我們以基金為對象,
使用交易模型模擬交易的過程。從實驗的結果中,第一個交易模型可在2004年1月1日
至2008年12月31日當中獲得9.11%的年化報酬率,相對於已存在的方法得到的6.89%的年
化報酬率,有更佳的結果。此外,第二個交易模型可得到與已存在的方法近似的年化報酬
率,但是相對第一個交易模型有較小的下跌風險。
Abstract
In this thesis, we propose two genetic-programming-based models that improve the
trading strategies for mutual funds. These two models can help investors get returns
and reduce risks. The first model increases the return by selecting funds with high
Sortino ratios and allocates the capital equally, achieving the best annualized return.
The second model also selects funds with high Sortino ratios, but reduces the risk
by allocating the capital with the mean variance model.
Most importantly, our model utilizes the genetic programming to generate
feasible trading strategies to gain return, which is suitable for the market that
changes anytime. To verify our models, we simulate the investment for mutual
funds from January 1999 to December 2009 (11 years in total). The experimental
results show that our first model can gain return from 2004/1/1 to 2008/12/31,
achieving the best annualized return 9.11%, which is better than the annualized
return 6.89% of previous approaches. In addition, our second model with smaller
downside volatility can achieve almost the same return as previous results.
