Do Investment Strategies Matter for Trading Global Clean Energy and Global Energy ETFs?

Abstract

Based on technological innovation and climate change, clean energy has been paid increasing attention to by worldwide investors, thereby increasing their interest in investing in firms that specialize in clean energy. However, traditional energy still plays an important role nowadays, because extreme weather has often occurred in the winters of recent years. We thus explore whether investing the strategies adopted by diverse technical trading rules would matter for investing in energy-related ETFs. By employing two representative global ETFs with more than 10 years of data, iShares Global Clean Energy ETF as the proxy of clean energy performance and iShares Global Energy ETF as that of traditional energy performance, we then revealed that momentum strategies would be proper for buying the green energy ETF, but contrarian strategies would be appropriate for buying the energy ETF. Furthermore, based on investment strategies adopted by diverse technical trading rules, we showed that the performance of clean energy outperforms that of energy, indicating that green energy does matter for the economy. Moreover, while observing the price trend of these two ETFs, we found that such two ETFs may have opposite share price performances, implying that, while the green energy ETF reached a relatively high price, investors following the contrarian strategies suggested in this study may reap profits by investing the energy ETF.

Furthermore, Shik and Chong [42] note that RSI trading rules can boost currency market risk-adjusted returns; Chong and Ng [43] show that investors can earn higher returns utilizing the RSI trading rule compared to a buy-and-hold strategy.…”

Navigating Energy and Financial Markets: A Review of Technical Analysis Used and Further Investigation from Various Perspectives

“…Technical analysis is precious in energy and financial markets due to their unique characteristics. These markets are impacted by a variety of factors, such as geopolitical shifts [32], supply and demand dynamics [33], and weather patterns [34], all of which can result in substantial price fluctuations [35][36][37]. This level of volatility makes it challenging to predict future price movements using only fundamental analysis since technical analysis may help investors make better decisions by analyzing price movements [38,39].…”

Testing of Portfolio Optimization by Timor-Leste Portfolio Investment Strategy on the Stock Market

“…In the short term, investors prefer momentum strategies because they can identify market opportunities and make quick profits. In the long term, on the other hand, investors prefer a contrarian strategy, which aims to buy stocks at a lower price and hold them until their value increases (Abukari and Otchere 2020;Day et al 2022;Mohapatra and Misra 2020). In addition, studies by Kassi et al (2019) showed that market risk has a significant impact on a company's financial performance.…”
