Blackstone Advisory Partners’ Byron Wien has released his annual list of “Surprises” for 2013, and as always he has some intriguing possibilities on the list.

Wien (who defines a “surprise” as an event which the average investor would only assign a one out of three chance of taking place but which he believes has a better than 50% likelihood of happening) offers several potential surprises that involve the economy and stock market. “A profit margin squeeze and limited revenue growth cause 2013 earnings for the Standard & Poor’s 500 to decline below $100, disappointing investors,” he writes in discussing one of them. “The S&P 500 trades below 1300. Companies complain of limited pricing power in a slow, highly competitive world economic environment.”

He also sees financial stocks have a tough time amid intense competition in commercial and investment banking, low trading volumes, increases in regulation, and lawsuits.

Chinese stocks will probably rise more than 20%, however, Wien adds, as “the new leaders in China seem determined to implement reforms to root out corruption, to keep the economy growing at 7% or better and to begin to develop improved health care and retirement programs.”
