Torsten Slok, chief economist at Deutsche Bank, is leaving to join alternative investment firm Apollo Global Management.
"After 15 years at Deutsche Bank, I am moving on to pursue another opportunity," Mr. Slok wrote in an email Thursday.
Mr. Slok, one of Wall Street's best known strategists, will join New York-based Apollo as its chief economist.
"We are thrilled to welcome Torsten Slok to Apollo," Scott Kleinman and Jim Zelter, co-presidents, said in an email. "We are confident his global expertise and diverse and highly regarded views on the market will be a valuable asset to our team and investors."
Apollo has $316 billion in assets under management.
Mr. Slok's research was well-followed on Wall Street, and his informative "weekend reading" and headline charts were a welcome respite from more wonky approaches to economic data. He frequently commented on the economy, fixed income, and interest rates to mainstream media, including Bloomberg News.
Prior to his time at the Deutsche Bank, Mr. Slok was an economist at both the Organization for Economic Cooperation and Development and the International Monetary Fund.
His coverage of U.S. and European economic developments at Deutsche will be shared by Chief U.S. Economist Matt Luzzetti, Chief European Economist Mark Wall, and Chief Economist for Germany Stefan Schneider under the direction of Peter Hooper, the firm's global head of economic research, Mr. Slok said.
Deutsche spokeswoman Maryanne Caruso declined to comment beyond Mr. Slok's email.
