Billionaire investor Warren Buffett has issued a stark warning about the future of the stock market, as concerns grow over a potential 12% market drop by October. Analysts point to a bearish trifecta contributing to the negative outlook. Additionally, there are rising concerns about the solvency of Bank of America, with some suggesting that the bank is underestimating credit risks, particularly in commercial real estate (CRE). Buffett's valuation signal, highlighted by Business Insider, is seen as a significant indicator of potential market instability. Earlier analysis from Q4 indicated that Bank of America saw zero risks in credit.
