Wharton Professor and author Jeremy Siegel thinks stocks will have another good year in 2013 — better than their surprisingly good 2012, in fact. Siegel tells Bloomberg that he thinks the main factor will be a rise in multiples. People will grow weary of near-zero yields on money market funds and low bond yields, and begin to realize that the world isn’t ending, he says, which will lead them back to stocks. “I have no fear that we’re overbought right now in the equity market,” he says. Siegel also says he expects to see some inflation going forward, which makes stocks a good place to be.
