Yesterday's big stocks drop may have just been the beginning.
Or so says HSBC Holdings Plc technical analyst Murray Gunn. In a new note, Gunn says he is now on alert for a big dip in U.S. equities. "With the U.S. stock market selling off aggressively on October 11, we now issue a RED ALERT," he writes. "The possibility of a severe fall in the stock market is now very high," he adds, noting that volatility has continued to rise since the end of the summer and the recent sell-off was seen across many areas of the market, and not just select groups.
