Investors should be buying bonds in all categories of U.S. securitized debt, in part because the market will continue to shrink next year, according to Bank of America Merrill Lynch analysts said. “We recognize that heading into 2011, recommending an overweight of all sectors of securitized products may appear exceedingly bullish,” the New York-based analysts led by Chris Flanagan wrote in a year-end outlook published Dec. 3. “However, the return performance for 2010 indicates that would have been the appropriate strategy for this past year.”
