This bullish momentum in a major healthcare stock has broader implications for risk sentiment across financial markets, including cryptocurrencies, as it signals confidence in traditional sectors. For crypto traders, such stock market events often correlate with shifts in institutional capital flows and risk appetite, potentially impacting Bitcoin (BTC), Ethereum (ETH), and related assets.
