The S&P 500 will get a double-digit percent lift from a "settlement" in the U.S.-China trade war, Wharton School professor Jeremy Siegel told CNBC on Tuesday.

"If we get some sort of settlement, I think we get a 10% pop, at least, in the S&P," the longtime stock bull said on "Closing Bell." "Otherwise, we're just going to be muddling along, because valuations are pretty full at this particular juncture, until we get some push on earnings."
