Abstract: The current study aims to explore the dynamic connectedness between stock and cryptocurrency markets and to determine the role of cryptocurrencies in the stock market as a hedge, diversifier, or safe haven. The study uses daily data of four stock indices and six cryptocurrencies, covering a period of January 2016 to December 2022. The analysis is conducted using the ADCC-GARC method with the wavelet coherency. The results indicate both stock and cryptocurrency markets exhibit long-run volatility persistence. The properties of Bitcoin, Ethereum, Binance Coin, Dogecoin, and Ripple vary between a range of hedges and diversifiers in different stock markets, which can change depending on market circumstances. However, only Tether has shown that it can act as a safe haven investment in all studied stock markets over time.
