VolTS: A Volatility-based Trading System to forecast Stock Markets Trend using Statistics and Machine Learning
Volatility-based trading strategies have attracted a lot of attention in
financial markets due to their ability to capture opportunities for profit from
market dynamics. In this article, we propose a new volatility-based trading
strategy that combines statistical analysis with machine learning techniques to
forecast stock markets trend.
The method consists of several steps including, data exploration, correlation
and autocorrelation analysis, technical indicator use, application of
hypothesis tests and statistical models, and use of variable selection
algorithms. In particular, we use the k-means++ clustering algorithm to group
the mean volatility of the nine largest stocks in the NYSE and NasdaqGS
markets. The resulting clusters are the basis for identifying relationships
between stocks based on their volatility behaviour. Next, we use the Granger
Causality Test on the clustered dataset with mid-volatility to determine the
predictive power of a stock over another stock. By identifying stocks with
strong predictive relationships, we establish a trading strategy in which the
stock acting as a reliable predictor becomes a trend indicator to determine the
buy, sell, and hold of target stock trades.
Through extensive backtesting and performance evaluation, we find the
reliability and robustness of our volatility-based trading strategy. The
results suggest that our approach effectively captures profitable trading
opportunities by leveraging the predictive power of volatility clusters, and
Granger causality relationships between stocks.
The proposed strategy offers valuable insights and practical implications to
investors and market participants who seek to improve their trading decisions
and capitalize on market trends. It provides valuable insights and practical
implications for market participants looking to

Logic-based Machine Learning for Transparent Ethical Agents
Autonomous intelligent agents are increasingly engaging in human
communities. Thus, they must be expected to follow social and ethical norms
of the community in which they are deployed in. In this work we present an
approach for developing such ethical agents which are able to develop ethical
decision making and judgment capabilities by learning from interactions with the
users. Our approach is a logic-based approach and the resulting ethical agents are
transparent by design
