Wharton School economics professor Jeremy Siegel said it before and he said it again on CNBC Wednesday: The Dow Jones Industrial Average will hit 15,000 by the end of next year.
"Take a look at earnings," he said on "Squawk Box." "Even before Apple last night, earnings are up 10 percent year-over-year. Expectations were all down to 2 percent."
Siegel said company earnings "are such a persuasive story on valuation for the market. Honestly, if you ask me what’s keeping the market down, I’m increasingly believing what Bernanke called…'the fiscal cliff' that’s coming at year end, with $500 billion worth of taxes and spending hits. I think that’s really keeping a lid on the market."
