Seif leaves BlackRock

Som Seif has left Toronto-based BlackRock Investments Canada Inc. Seif joined BlackRock in January after the firm entered into an agreement to acquire the controlling stake in Claymore Investments Inc. from Guggenheim Partners LLC., a global financial services firm based in New York. Seif had founded Claymore in 2005 and been its CEO and president. While the deal was made final in March, Seif remained with BlackRock until mid-April to assist with the transition of the acquisition. His decision to leave BlackRock came days after the firm’s April announcement that it would be rebranding all of Claymore’s products under the iShares name. Seif, now 35, built Claymore from a basement operation to $8 billion in assets under management in only six years.
