Stock-market guru Jeremy Siegel sees a “Goldilocks situation” for the recent raging bull stock market to continue.

"I actually think we have a Goldilocks situation going on now," he recently told CNBC. "We have everything moving in tandem," said the finance professor at the University of Pennsylvania's Wharton School,  

Siegel’s enthusiasm has yet to wane despite a 12 percent rally in the past six months, and nearly a tripling of the S&P 500 over the past eight years.

"But much more important than that is the maintained or upward guidance for second, third and fourth quarter — something we've not had for years," he said.

"It's been stunning how year estimates have come way down by the time we get to December. Now, anything can happen. We're only in April — but it's the first time that I have seen forward guidance maintained or increased since we turned around from the great crisis back in 2009," said Siegel, most famous for penning a classic of popular investment literature, "Stocks for the Long Run."

Siegel isn't alone in his optimism.

David Horowitz, author of the best-selling book "Big Agenda: President Trump's Plan to Save America," told Newsmax TV that the market rally since Republican Donald Trump won the election has more room for gains as the president pushes his pro-business agenda.

“There's more upside. Starting from when he was president-elect he started this stock market boom,” he told “The Income Generation Show.”

“There will be corrections. There are going to be setbacks along the way like the healthcare which they hurried too fast. If you're looking over the long term of this administration I think the stock market is going to love Trump.”
