All three major indexes (^DJI,^GSPC, ^IXIC) jump in premarket trading after former President Donald Trump secured a second term, winning the presidential election against Vice President Kamala Harris. American Action Forum president and the former director of the Congressional Budget Office from 2003 to 2005, Doug Holtz-Eakin, joins Julie Hyman and Seana Smith to discuss the expected economic impacts of Trump's win and why it's sending US stocks higher.

"Certainly the most striking difference between the Biden administration, and what probably would have been the Harris administration, and Mr. Trump is in the regulatory area. The Biden administration has imposed $1.7 trillion of costs on the private sector in not yet four years. That's double what Obama did in eight years. During his four years as president, Donald Trump imposed $40 billion [in] regulatory costs. It's just night and day different on the regulatory front. There's no reason to believe that that will be any different the next time around," Holtz-Eakin tells Yahoo Finance.

He adds there's "the unambiguous good news of extending the tax cuts, perhaps getting lower corporate rate as well," though "the question of what happens on the tariff front" persists as with Trump's plans representing "a headwind to growth." Holtz-Eakin says assessing the impact of Trump's tariff plans will depend on which party controls of the House.

Another significant impact of Trump's reelection is on immigration. "There will be attempts to change the legal immigration system to minimize immigration to the US. Deportations are a wild card. He promised to deport 11 million people in the 2016 race. That never transpired. We did some work back then that said it would cost $400 [billion] or $500 billion and take about 20 years. None of that played out at all, so I've got an eye on that as well." The immigration plans Trump campaigned on could affect the labor market and, in turn, inflationary pressures.
