Investors are entering 2011 in a relatively bullish mood, raising equity holdings to a 10-month high, increasing exposure to high-yield credit and cutting back on government debt, Reuters polls showed on Wednesday.

Within bond portfolios, however, concern about the cost of US Treasuries and the stability of euro zone debt, did not show up dramatically.   

Allocations to emerging market debt were cut instead.

Surveys of 55 leading investment houses in the United States, Europe ex UK, Japan and Britain showed investors holding 54.1 percent of a typical mixed-asset portfolio in stocks in December.

That was up from 53.2 percent in November and the highest since 55.4 percent in February.   

Bonds were cut to 33.9 percent, the lowest since February, from 34.2 percent in November. Cash was at 3.9 percent, down from 4.6 percent.   

A combination of improving economic data and a belief in future, robust, corporate earnings has lifted investor appetite for equities over the past few months. The MSCI all-country world stock index was flirting with levels last seen in September 2008 on Wednesday.

"People are coming off the sidelines and buying stocks," said Keith Wirtz, president and chief investment officer at Fifth Third Asset Management in Cincinnati.   

There was also sign of risk appetite in an increased exposure to riskier, higher yield bonds. At the same time concerns have risen that yields on benchmarket government bonds are too low, providing little return and threatening a sell-off.

Investors in the Reuters polls did cut back overall exposure to bonds. But when it came to the money left for bonds they favoured US and euro zone government debt over most emerging markets, which have been very popular this year.   

Exposure to emerging market debt was 8.1 percent of a bond portfolio for the month, compared with 9.6 percent a month earlier.

Investors also regained some composure about euro zone government bonds following the crisis over Ireland's debt. They raised exposure within a bond portfolio to 31.5 percent from 31.2 percent, although these numbers remain well below the more than 42 percent seen at the beginning of 2010.

US fund managers built up their equity holdings in December to one of the highest points this year on signs of a swifter economic recovery.   

The poll, which surveyed 13 US-based fund management companies, showed firms boosting their equity allocations for the fourth month in a row to an average of 65.0 percent, two percentage points over November.   

The Reuters poll also showed money managers scaling back their exposure to bonds for a fourth consecutive month, to 27.9 percent of their portfolios in December, compared with 30.2 percent last month. - Reuters
