Coming off the 10th best year ever for the S&P 500, investors have to wonder if it isn't time to start taking some money off the table.
What does Wharton Professor Jeremy Siegel think?
He thinks 2014 will be a very good year, but not anything like 2013.
He bases this on the fact that three big concerns for the market have been removed/lessened (taper concerns, Iran, government shutdown).
Siegel sees a 10% to 15% upside in 2014.
