Blackstone Vice Chairman Byron Wien warns savvy investors that a correction is coming in the first half of 2018.

“Right now we are in a very frothy period,” Wien recently told Fox Business Network.

“Right now I think the market is getting dangerous.”

Wien warns investors that they shouldn't become overconfident.

“I see investor sentiment at an all-time high, I see interest rates rising, I see more inflation on the horizon,” Wien said.

“I see a plethora of good news, but I see people discounting it. Now we’ve gotten to the point where valuations are extreme. Don’t get me wrong I think we’ll have a positive year in 2018, but right now I’d say we are vulnerable,” he warned.

Wien thinks the Federal Reserve will hike interest rates four times this year.

“I think they can do it because the economy can handle it,” he said. “The economy is growing at three percent. Obama would have killed for three percent.”

Wien says the economy has plenty of strength and interest rates are way below their normal rate.

Wien favors technology, biotech and energy.

Meanwhile, Wall Street is warming up to Trump, Bloomberg reported.

Jamie Dimon and Lloyd Blankfein gave credit to the U.S. president Wednesday for policies that they said will help boost economic growth and drive markets higher.

“I like a lot more stuff than I don’t like,” Blankfein, chief executive officer of Goldman Sachs Group Inc., said in an interview on CNBC at the World Economic Forum in Davos, Switzerland.

“I’ve really liked what he’s done for the economy and I think he’s gone out of his way to be very, very supportive of the system. And I don’t want to be antagonistic to them. And frankly, I want to honor that.”

Dimon, who runs JPMorgan Chase & Co., said he’s focusing on policy issues rather than the rhetoric coming out of the administration.

“What I’m bulled up about is that policy makers are making good policy decisions in the U.S. about taxes, about proper regulatory reform,” Dimon said in a Bloomberg Television interview at the Swiss ski resort, where Trump plans to arrive on Thursday morning.

Banks have been encouraged by efforts to soften regulations and by corporate tax cuts that are expected to give the largest lenders a windfall of more than $10 billion. Regulators are working to ease banks’ leverage-ratio requirements and the Volcker Rule, which limits the firms’ ability to trade for their own accounts.
