Norwegian Cruise Line soared 32 percent in its first day of trading, the top performance of the three companies making their public debut on Friday.

Analysts forecast that companies in the S&P 500 will report a 4 percent increase in fourth-quarter earnings over the same period the year before, according to a report out Friday from S&P Capital IQ.
