Abstract
In recent decades, financial quantification has emerged and matured rapidly.
For financial institutions such as funds, investment institutions are
increasingly dissatisfied with the situation of passively constructing
investment portfolios with average market returns, and are paying more and more
attention to active quantitative strategy investment portfolios. This requires
the introduction of active stock investment fund management models. Currently,
in my country's stock fund investment market, there are many active
quantitative investment strategies, and the algorithms used vary widely, such
as SVM, random forest, RNN recurrent memory network, etc. This article focuses
on this trend, using the emerging LSTM-GRU gate-controlled long short-term
memory network model in the field of financial stock investment as a basis to
build a set of active investment stock strategies, and combining it with SVM,
which has been widely used in the field of quantitative stock investment.
Comparing models such as RNN, theoretically speaking, compared to SVM that
simply relies on kernel functions for high-order mapping and classification of
data, neural network algorithms such as RNN and LSTM-GRU have better principles
and are more suitable for processing financial stock data. Then, through
multiple By comparison, it was finally found that the LSTM- GRU gate-controlled
long short-term memory network has a better accuracy. By selecting the LSTM-GRU
algorithm to construct a trading strategy based on the Shanghai and Shenzhen
300 Index constituent stocks, the parameters were adjusted and the neural layer
connection was adjusted. Finally, It has significantly outperformed the
benchmark index CSI 300 over the long term. The conclusion of this article is
that the research results can provide certain quantitative strategy references
for financial institutions to construct active stock investment portfolios.
