High-low Strategy of Portfolio Composition using Evolino RNN Ensembles
trategy of investment is important tool enabling better investor's decisions in uncertain finance market. Rules of portfolio selection help investors balance accepting some risk for the expectation of higher returns. The aim of the research is to propose strategy of constructing investment portfolios based on the composition of distributions obtained by using high–low data. The ensemble of 176 Evolino recurrent neural networks (RNN) trained in parallel investigated as an artificial intelligence solution, which applied in forecasting of financial markets. Predictions made by this tool twice a day with different historical data give two distributions of expected values, which reflect future dynamic exchange rates. Constructing the portfolio, according to the shape, parameters of distribution and the current value of the exchange rate allows the optimization of trading in daily exchange-rate fluctuations. Comparison of a high-low portfolio with a close-to-close portfolio shows the efficiency of the new forecasting tool and new proposed trading strategy

Faculty of Engineering and the Built EnvironmentDue to the volatile nature of the world economies, investing is crucial in ensuring an individual is prepared for future
financial necessities. This research proposes an application, which employs computational intelligent methods that could
assist investors in making financial decisions. This system consists of 2 components. The Forecasting Component (FC) is
employed to predict the closing index price performance. Based on these predictions, the Stock Quantity Selection
Component (SQSC) recommends the investor to purchase stocks, hold the current investment position or sell stocks in
possession. The development of the FC module involved the creation of Multi-Layer Perceptron (MLP) as well as Radial
Basis Function (RBF) neural network classifiers. TCategorizes that these networks classify are based on a profitable trading
strategy that outperforms the long-term “Buy and hold” trading strategy. The Dow Jones Industrial Average, Johannesburg
Stock Exchange (JSE) All Share, Nasdaq 100 and the Nikkei 225 Stock Average indices are considered. TIt has been
determined that the MLP neural network architecture is particularly suited in the prediction of closing index price
performance. Accuracies of 72%, 68%, 69% and 64% were obtained for the prediction of closing price performance of the
Dow Jones Industrial Average, JSE All Share, Nasdaq 100 and Nikkei 225 Stock Average indices, respectively. TThree
designs of the Stock Quantity Selection Component were implemented and compared in terms of their complexity as well as
scalability. TComplexity is defined as the number of classifiers employed by the design. Scalability is defined as the ability of
the design to accommodate the classification of additional investment recommendations. TDesigns that utilized 1, 4 and 16
classifiers, respectively, were developed. These designs were implemented using MLP neural networks, RBF neural
networks, Fuzzy Inference Systems as well as Adaptive Neuro-Fuzzy Inference Systems. The design that employed 4
classifiers achieved low complexity and high scalability. As a result, this design is most appropriate for the application of
concern. It has also been determined that the neural network architecture as well as the Fuzzy Inference System
implementation of this design performed equally well

TM-vector: A Novel Forecasting Approach for Market stock movement with a Rich Representation of Twitter and Market data
Stock market forecasting has been a challenging part for many analysts and
researchers. Trend analysis, statistical techniques, and movement indicators
have traditionally been used to predict stock price movements, but text
extraction has emerged as a promising method in recent years. The use of neural
networks, especially recurrent neural networks, is abundant in the literature.
In most studies, the impact of different users was considered equal or ignored,
whereas users can have other effects. In the current study, we will introduce
TM-vector and then use this vector to train an IndRNN and ultimately model the
market users' behaviour. In the proposed model, TM-vector is simultaneously
trained with both the extracted Twitter features and market information.
Various factors have been used for the effectiveness of the proposed
forecasting approach, including the characteristics of each individual user,
their impact on each other, and their impact on the market, to predict market
direction more accurately. Dow Jones 30 index has been used in current work.
The accuracy obtained for predicting daily stock changes of Apple is based on
various models, closed to over 95\% and for the other stocks is significant.
Our results indicate the effectiveness of TM-vector in predicting stock market
direction.Comment: 24 pag
Managing extreme cryptocurrency volatility in algorithmic trading: EGARCH via genetic algorithms and neural networks.
Política de acceso abierto tomada de: https://www.aimspress.com/index/news/solo-detail/openaccesspolicyThe blockchain ecosystem has seen a huge growth since 2009, with the introduction of
Bitcoin, driven by conceptual and algorithmic innovations, along with the emergence of numerous new
cryptocurrencies. While significant attention has been devoted to established cryptocurrencies like
Bitcoin and Ethereum, the continuous introduction of new tokens requires a nuanced examination. In
this article, we contribute a comparative analysis encompassing deep learning and quantum methods
within neural networks and genetic algorithms, incorporating the innovative integration of EGARCH
(Exponential Generalized Autoregressive Conditional Heteroscedasticity) into these methodologies. In
this study, we evaluated how well Neural Networks and Genetic Algorithms predict “buy” or “sell”
decisions for different cryptocurrencies, using F1 score, Precision, and Recall as key metrics. Our
findings underscored the Adaptive Genetic Algorithm with Fuzzy Logic as the most accurate and
precise within genetic algorithms. Furthermore, neural network methods, particularly the Quantum
Neural Network, demonstrated noteworthy accuracy. Importantly, the X2Y2 cryptocurrency
consistently attained the highest accuracy levels in both methodologies, emphasizing its predictive
strength. Beyond aiding in the selection of optimal trading methodologies, we introduced the potential
of EGARCH integration to enhance predictive capabilities, offering valuable insights for reducing
risks associated with investing in nascent cryptocurrencies amidst limited historical market data. This
research provides insights for investors, regulators, and developers in the cryptocurrency market.
Investors can utilize accurate predictions to optimize investment decisions, regulators may consider implementing guidelines to ensure fairness, and developers play a pivotal role in refining neural
network models for enhanced analysis.This research was funded by the Universitat de Barcelona, under the grant UB-AE-AS017634

Portfolio formation with preselection using deep learning from long-term financial data
Portfolio theory is an important foundation for portfolio management which is a well-studied subject yet not fully conquered territory. This paper proposes a mixed method consisting of long short-term memory networks and mean-variance model for optimal portfolio formation in conjunction with the asset preselection, in which long-term dependences of financial time-series data can be captured. The experiment uses a large volume of sample data from the UK Stock Exchange 100 Index between March 1994 and March 2019. In the first stage, long short-term memory networks are used to forecast the return of assets and select assets with higher potential returns. After comparing the outcomes of the long short-term memory networks against support vector machine, random forest, deep neural networks, and autoregressive integrated moving average model, we discover that long short-term memory networks are appropriate for financial time-series forecasting, to beat the other benchmark models by a very clear margin. In the second stage, based on selected assets with higher returns, the mean-variance model is applied for portfolio optimisation. The validation of this methodology is carried out by comparing the proposed model with the other five baseline strategies, to which the proposed model clearly outperforms others in terms of the cumulative return per year, Sharpe ratio per triennium as well as average return to the risk per month of each triennium. i.e. potential returns and risks
An adaptive network-based approach for advanced forecasting of cryptocurrency values
This paper describes an architecture for predicting the price of
cryptocurrencies for the next seven days using the Adaptive Network Based Fuzzy
Inference System (ANFIS). Historical data of cryptocurrencies and indexes that
are considered are Bitcoin (BTC), Ethereum (ETH), Bitcoin Dominance (BTC.D),
and Ethereum Dominance (ETH.D) in a daily timeframe. The methods used to teach
the data are hybrid and backpropagation algorithms, as well as grid partition,
subtractive clustering, and Fuzzy C-means clustering (FCM) algorithms, which
are used in data clustering. The architectural performance designed in this
paper has been compared with different inputs and neural network models in
terms of statistical evaluation criteria. Finally, the proposed method can
predict the price of digital currencies in a short time.Comment: 11 page
