Systematic trend-following strategies applied to equity markets are widely studied, yet most reported performance statistics are non-reproducible in live trading. This paper makes three contributions. First, we introduce a formal taxonomy of look-ahe...
This review paper thoroughly examines the role of technical analysis in energy and financial markets with a primary focus on its application, effectiveness, and comparative analysis with fundamental analysis. The discussion encompasses fundamental pr...
In Kwon and Satchell (2018), a theoretical framework was introduced to investigate the distributional properties of the cross-sectional momentum returns under the assumption that the vector of asset returns over the ranking and holding periods were m...
We analyze a novel alpha momentum strategy that invests in stocks based on three-factor alphas which we estimate using daily returns. The empirical analysis for the U.S. and for Europe shows that (i) past alpha has power in predicting the cross-secti...
Most adversarial attack methods achieve high success rates under the white-box setting. However, these methods often lack transferability when targeting other deep neural network (DNN) models. Momentum-based attacks have emerged as an effective strat...
Economic policy uncertainty has been identified as a new macroeconomic risk factor that harms the stock market’s profitability. This paper examines the impact of the Chinese EPU levels on one of the most famous financial anomalies—momentu...

Although the hub blockage effect is generally disregarded for large-sized horizontal axis wind machines, it can significantly affect the performance of small-sized turbines whose ratio between the hub and rotor radii can attain values up to 25–...
Momentum and reversal effects are important phenomena in stock markets. In academia, relevant studies have been conducted for years. Researchers have attempted to analyze these phenomena using statistical methods and to give some plausible explanatio...
Although the evolutionary pathways are critical to the success of platforms, extant literature has provided little insight into the dynamic processes of the platform evolution, let alone how platforms constitute the evolutionary pathways over time. A...
From a sustainable development perspective, continuous industrial growth is an important issue. In recent years, it has become difficult for companies to survive in an increasingly competitive and rapidly changing business environment. To align with...
In static conditions, the only mechanism available for sludge/water separation is sludge sedimentation by gravity. In dynamic conditions an additional mechanism is available: sludge momentum preservation. In order to achieve a better understanding of...
After diversification, periodic portfolio rebalancing has become one of the most widely practiced methods for reducing portfolio risk and enhancing returns. Most of the rebalancing strategies found in the literature are generally regarded as contrari...
This paper proposes a momentum envelope design strategy for a satellite equipped with control moment gyroscopes (CMGs). The objective is to improve spacecraft maneuverability while preserving singularity-free operation of a roof-array CMG assembly. T...
In this Opinion, the importance of public awareness to design solutions to mitigate climate change issues is highlighted. A large-scale acknowledgment of the climate change consequences has great potential to build social momentum. Momentum, in turn,...
