(Reuters) - Investors have turned away from riskier assets, favouring U.S. stocks, as concerns about the euro zone debt crisis resurface and expectations for global growth are scaled back, a closely-watched fund managers' survey showed on Tuesday. 

As a result, many funds now hold a slightly higher proportion of assets in cash, and more have shifted out of European equities and cut their bond holdings, the monthly poll from Bank of America Merrill Lynch (BofAML) showed.

 

Due to the weaker growth outlook, the poll found many more investors are predicting the U.S. Federal Reserve and the European Central Bank (ECB) will loosen policy further through the use of quantitative easing measures, known as QE.
