Global investors raised allocations to U.S. and British equities in November and lifted weightings of selected emerging market assets to multi-year highs as some managers positioned for a potential rebound in the sector. The survey of 50 fund managers and chief investment officers in the United States, Europe, Britain, Japan and China was conducted between Nov. 17 and 26.
