President-elect Donald Trump will last no more than four years in the White House, a period when corporations and Wall Street will retain the upper hand over the struggling workers who helped elect him in a populist wave, bond manager Bill Gross of Janus Capital Group Inc (JNS.N) said on Wednesday.

In his monthly investment outlook, “Populism Takes a Wrong Turn,” Gross also said “there is no new Trump bull market in the offing,” and that global diversified investors should be “satisfied” with 3 percent to 5 percent annual returns.

“The Trumpian Fox has entered the Populist Henhouse, not so much by stealth but as a result of Middle America’s misinterpretation of what will make America great again,” Gross wrote.

“[Trump’s] tenure will be a short four years but is likely to be a damaging one for jobless and low-wage American voters,” Gross added. “I write in amazed, almost amused bewilderment at what American voters have done to themselves.”

Gross became the world’s most famous bond fund manager at Allianz SE’s (ALVG.DE) Pacific Investment Management Co, where he ran Pimco Total Return (PTTRX.O) and worked until 2014, when he joined Janus.
