Rockefeller Capital hires an ex-Morgan Stanley strategist as it expands globally.

Rockefeller Capital Management, a financial advisory firm that oversees $95 billion in assets, has hired a former Morgan Stanley strategist, Ruchir Sharma, to help expand its global business.

Mr. Sharma, 47, will become the chairman of Rockefeller’s international business on Monday and will form an investment company, Breakout Capital, in partnership with Rockefeller, the company announced on Thursday.

Known for his market commentary, including as a contributor to The New York Times’s Opinion section, Mr. Sharma spent the past 25 years in Morgan Stanley’s investment-management division, most recently serving as chief global strategist and head of emerging markets. At Rockefeller, he will report to Gregory Fleming, the chief executive, and will join the firm’s management committee.

Rockefeller’s global expansion fits in with Mr. Sharma’s longer-term view that U.S.-based investments, like stocks and the dollar, have become overvalued after outperforming much of the rest of the world in recent years.

“We are at peak America,” Mr. Sharma said in an interview. “This decade could be much better for international investors,” with prospects in economies such as Brazil, Vietnam, India and Poland that are more attractive than the United States, he said.

Mr. Fleming, who previously ran Morgan Stanley’s wealth and investment-management divisions, said Mr. Sharma would bring investing skills and “intellectual firepower” to Rockefeller. “His position reinforces our commitment to the global markets,” Mr. Fleming said in a statement.
