This paper examines the relationship between the US National Financial Conditions Index (NFCI) and the clean energy industry using quantile and frequency connectedness, cross-quantile, and wavelet quantile correlation (WQC) techniques. Results reveal (a) a stronger dependence between the NFCI and clean energy under bullish market states. Moreover, the total connectedness between the NFCI and clean energy mostly exhibits time-varying characteristics. In particular, clean energy has a greater spillover effect than the NFCI. (b) Dynamic frequency total connectedness at extreme quantiles provided a more comprehensive view of structural shocks in financial markets, and major crises, such as COVID-19, significantly amplified this connectedness. Overall, the WilderHill Clean Energy Index and the NASDAQ OMX Renewable Energy Index demonstrate substantial potential for hedging financial conditions. (c) The cross-quantile correlation results revealed an asymmetric dependency, demonstrating a sustained significant positive relationship between the NFCI and clean energy index (CEI) across the relative higher quantiles and middle quantiles. The WQC showed that the NFCI and specific CEIs tended to exhibit the strongest positive correlations in nonextreme quantiles and lower frequencies. These results can be of considerable interest to various financial market participants.

CEO narcissism is an established fact in the corporate world. We argue that uncertainty moderates the relationship between CEO narcissism and corporate performance. Thus, we hypothesize that the decisiveness and craving for attention of the narcissistic CEO improve corporate performance during periods of high uncertainty, while these features of narcissism are not needed and indeed are disadvantageous during periods of low uncertainty. Our empirical results support our hypothesis. Our findings are important in understanding the context specificity of the advantages and disadvantages of CEO narcissism in an empirical corporate setting and thus important for CEO selection and CEO management.
