COMBINED INVESTMENTS IN INTERDEPENDENT SECTORS: A STRATEGIC APPROACH TO ENHANCING INVESTMENT EFFECTIVENESS UNDER HIGH MARKET VOLATILITY

This study investigates the theoretical underpinnings and empirically validated effectiveness of combined investments in interdependent sectors – namely energy, digital technologies, and cryptoassets – within the context of heightened financial market volatility and structural transformations in the global economy. The principal objective is to substantiate the hypothesis that cross-sectoral investment strategies generate a multiplicative effect on return generation and risk mitigation, outperforming conventional portfolio models. The analysis confirms the existence of significant intersectoral linkages among the energy, IT, and crypto markets, as evidenced by synchronized index movements, correlated capital flows, and underlying technological complementarities. Empirical results demonstrate both short- and long-term causal and correlational relationships among these sectors, indicating the presence of a compensatory-multiplicative mechanism that enhances structural diversification and contributes to overall portfolio stability. A conceptual framework, denoted the “Investment Energy Asset” (IEA), is introduced as a synthetic construct integrating sector-specific strengths. Backtesting reveals the superior performance of portfolios containing IEAs: the crypto-energy combination yields an Investment Value Index (IVI) of 3.19x and a Value Retention Index (VRI) of 1.042x, surpassing traditional benchmarks such as the S&P 500. The IEA exhibits a balanced performance profile, with an IVI of 2.55x and a VRI of 1.027x. Regression analysis confirms the presence of a stable intersectoral transmission channel, with β coefficients of 1.05 for cryptoassets and 1.03 for the IEA. Combined investments in interdependent sectors are shown to provide strategic advantages through sectoral synergy, embedded structural flexibility, and effective risk compensation. The IEA framework enables investors to construct adaptive, high-performing portfolios capable of maintaining resilience in the face of extreme volatility, technological shifts, and macroeconomic disruptions.
