Russ Koesterich, the global investment strategist for BlackRock’s iShares ETF unit, was named to the additional post of chief investment strategist of BlackRock, a newly created post in which he will report to Ken Kroner, BlackRock’s global head of Multi-Asset Strategies.

Koesterich will retain his post at iShares, the world’s biggest exchange-traded fund company, BlackRock said today in a press release. A number of other individuals play investment strategist roles in different parts of BlackRock, and Koesterich won’t oversee them in his new post, a BlackRock spokeswoman told IndexUniverse.

In his new role, Koesterich will focus on communicating BlackRock’s investment strategy and perspective on the markets and economy to investors and financial advisors, the company said.

“In this new role, Russ will focus on communicating the best thinking to investors from throughout BlackRock, drawing on the full range of BlackRock’s capabilities across geographies, investment strategies and asset classes,” BlackRock President Robert Kapito said in the prepared statement.

BlackRock in the world’s biggest asset manager, with $3.67 trillion across equity, fixed income, cash management, alternative investment, real estate and advisory strategies. BlackRock's iShares has more than $517 billion in assets, according to data compiled by IndexUniverse.
