HONG KONG : The California State Teachers' Retirement System (CalSTRS), the second-largest U.S. pension fund, said on Tuesday it had shortlisted 19 fund managers for its China stock portfolio. "We have identified 19 managers for our China public equity pool. Placement in this pool does not guarantee a manager will receive an allocation," the firm said a statement to Reuters that did not disclose the names of the managers. It said actual allocation sizes to the selected managers would be decided on factors including CalSTRS' needs and the overall attractiveness of the Chinese market.
