Аннотация
Мы впервые выявляем взаимосвязи между ценами на нефть «Brent» и природный газ и индексами акций компаний с высокими ESG-рейтингами во временной и частотной областях. Мы применяем такие методы вейвлет-анализа, как анализ квадратичной вейвлет-когерентности и разности фаз между рядами данных. Исследование строится на ежедневных данных с 2018 по начало 2024 г., что позволяет охватить периоды относительной макроэкономической стабильности (до 2020 г.), пандемии коронавируса COVID-19 (2020–2021 г.) и роста геополитической напряженности в мире (с 2022 г.). Мы рассматриваем ESG-индексы глобального рынка, рынков США и ЕС. В нашем исследовании показаны области низкой и высокой согласованности цен на энергоресурсы и ESG-ориентированных индексов для трех рассматриваемых периодов, выявлены соотношения запаздывания и опережения между рассматриваемыми классами активов. Выявление областей низкой согласованности позволяет разработать стратегии диверсификации инвестиций, в том числе для хеджирования от падений цен на нефть и газ в условиях глобальных кризисов. Мы пришли к выводу, что индексы акций компаний–лидеров ESG глобального рынка и рынка США предоставляют возможности для диверсификации инвестиций во фьючерсы на природный газ.
