According to Evan (@StockMKTNewz), UnitedHealth Group (UNH) is currently under criminal investigation for possible Medicare fraud, as reported by the Wall Street Journal. This development has triggered immediate volatility in healthcare sector stocks, with UNH experiencing sharp pre-market declines. For crypto traders, the news is relevant as heightened uncertainty and risk aversion in traditional equity markets often lead to increased interest in digital assets as alternative investments.
