Most millionaires expect a bullish market in 2007, with yields of 6 to 10 percent, according to a study released January 24 by Northern Trust. The survey showed that 62 percent of millionaires expect the market to make gains of at least 6 percent, while only 6 percent of respondents believe the market will register losses.

Stoking the confidence is the belief that corporate earnings will remain strong in 2007. Thirty-one percent of the respondents reported they were “very optimistic” about earnings, while 26 percent called themselves “very optimistic” that the economic expansion will continue.
