The current study analysed five green indices (BIST, CSI, DJSI, S&P ESG, STOXX) and five conventional indices (DJIA, S&P 500, FTSE 100, China, KOSPI) to explore their time-varying volatility and correlation. The results reveal that BIST exhibits the highest volatility, suggesting exposure to speculative movements, while DJSI demonstrates greater stability, reflecting the resilience of sustainability leaders in developed markets. Despite its relatively high volatility, the China index remains a viable instrument for diversification. The KOSPI index emerged as a balanced option, offering moderate volatility and correlation, while the S&P ESG index was positioned as a comparatively safer investment due to its stable performance and moderate comovement with conventional indices. The pairing of CSI and the China index was identified as optimal for risk-averse investors, driven by their consistently low correlation throughout the study period, as identified by the CWT analysis.
