Despite three months of economic and corporate data, clarity on health care legislation and the S&P 500’s steady climb to an 18-month high, the outlook for the rest of 2010 is no clearer than when the first quarter began, according to many investors, traders and strategists.

A survey given to institutional investors at a Strategas Research Partners conference last week featured guesses for the S&P 500’s level 12 months from now that ranged from 1400 to 900. The range of predictions for the 10-year yield was between 6.5 percent and 2.5 percent. The crowd thought gold could be anywhere from $800 to $1800.
