NEW YORK (TheStreet) -- President-elect Donald Trump will bring "major changes" to the U.S. economy that will move it in the right direction, Billionaire and Icahn Enterprises Chairman Carl Icahn said on CNBC's "Halftime Report" on Wednesday afternoon. 

"I'm certainly happy about it. I really think it's a very important thing for our economy in general," he said. 

If you go down one path for too long, you eventually need change, Icahn said. "You know I've been very hedged. Now is the first time that I think that there is a chance for our economy to come out of this."

When Icahn was at the celebration for Trump's victory last night, he noticed the market going down around 11:30 p.m. and left to go buy stocks on the dip, he said. Last night, Dow Industrials futures briefly plunged 800 points.

"I saw that market going down like insanity, and I personally don't believe that Trump is bad for the market necessarily, so I left and went home and I bought a lot of stock in the overnight market," he explained. 

This morning, Icahn is still glad he did that, he said. "I guess that's what makes me happy too."

Trump is a "real smart guy," who "won't be so terrible" for our economy and won't do "crazy" things, Icahn claimed.
