You may have heard that some people are concerned about Donald Trump being, at best, enamored with Russian president Vladimir Putin and, at worst, Putin’s puppet. Wherever the truth may lie, the announcement from the U.S. Treasury today that it will “allow for some companies to do limited business with Russia’s Federal Security Service” (i.e., a modification of Russian sanctions put in place by the Obama administration) can only do wonders for the transatlantic bromance. Oh, and the Russian stock market liked it, too! Per Marketwatch:

The Russian ruble and its stock market jumped on Thursday after media reports that the Treasury Department would ease sanctions on Russia's intelligence agency. The dollar fell more than 2% against the ruble after the initial reports, but soon recovered some of that decline after President Donald Trump’s press secretary Sean Spicer denied that sanctions had been lifted. Still, the greenback was off 1.5% at 59.18 rubles, on track for its second-worst daily performance of the year. Russian stocks also soared on the news. The iShares MSCI Russian Capped ETF rose 1% to $34.22. Trump has repeatedly praised Russian President Vladimir Putin while also criticizing the North Atlantic Treaty Organization.

Russia E.T.F.s have been on a tear since Trump’s election in November, given his long history of comments about easing economic sanctions on Russia and the large number of Russia-affiliated advisers in his orbit. Vaneck Vectors Russia E.T.F. is up more than 15 percent since Election Day, while Direxion’s Daily Russia Bull & Bear 3x Shares fund is up about 60 percent. iShares MSCI Russia Capped jumped about 50 percent on November 9 alone.

Another billionaire tires of Trump

In October 2015, billionaire real-estate investor Sam Zell told CNBC that while Donny Trump was a “very accomplished person,” he doubted the guy had “the temperament and the personality to be the president of the United States.” A week after Trump was elected, Zell, like so many business leaders, shrugged off the fact that a 70-year-old man with the temperament of a person one-tenth that age is was now in charge of the country—thanks in no small part to the alleged positive influence he would have on the economy. Now, following the events of the past weekend, Zell’s not feeling super great about the fellow real-estate billionaire being in power.

“The United States has been the leader in the world for 200 years because it’s had a very aggressive immigration policy,” Zell told attendees of annual Tiger 21 conference on Thursday, according to Bloomberg. “I think that this current period of anti-immigration is very dangerous to the future of our country.”
