Chinese shares bounced back from their earlier lows on Monday as weak China factory activity reinforced views that Beijing will roll out more stimulus measures to support its slowing economy. The HSBC final Purchasing Managers' Index fell to 48.9, its fastest drop in a year, down from the preliminary reading of 49.2 and weakening from the 49.6 print in March. Meanwhile, the IMF is close to declaring China's yuan as fairly valued for the first time in more than a decade, a milestone that follows years of IMF censure of Beijing's management of the currency.
