"Experts warn of banking crisis and recommend stocks to buy in case of market downturn"

Wall Street has downgraded European banks and named stocks to buy in case the markets turn sour. The move comes as investors worry about the impact of rising bond yields on the global economy. The downgrades are expected to hit banks in Germany, France, and Italy the hardest. Meanwhile, investors are being advised to buy stocks in sectors such as technology, healthcare, and consumer staples.
