Morgan Stanley strategist Michael Wilson is once again bearish on the US stock market. Returning to the bearish camp, Wilson, a well-known skeptic of the American stock market, believes that the recent uptrend has fully realized his previous predictions, and investors are best off taking profits now. 'We are bearish again,' he and his colleagues wrote in a report on Monday. They expect the S&P 500 index to resume its decline after breaking above the 200-day moving average last week, stating that the downward trend since the beginning of the year remains intact. They wrote: 'This makes the risk-return of betting on further increases quite low.' One forecast marks a shift in Wilson's viewpoint. As recently as last week, he also believed that tactical recovery might continue until December, pressured next year by weak corporate earnings.
