BlackRock, the world's largest asset manager, reported a better-than-expected quarterly profit on Wednesday as investors poured more money into the company's funds, driving robust fee growth and boosting its assets under management to a record high. 

BlackRock's assets under management jumped to a record $9.49 trillion in the second quarter from $7.32 trillion a year earlier. 

"More than ever, our voice is resonating deeper and more broadly with our clients worldwide," BlackRock's chief executive, Larry Fink, said in an interview. 

The company continued to gather assets at a robust pace as investors deployed money across BlackRock's product types and asset classes. 

Global equity markets' strength during the second quarter helped boost both assets under management as well as fee growth. 

The U.S. economy displayed signs of a recovery over the past quarter, helped by large government stimulus and steady vaccination programs. Global financial markets continue to display strength a year after the coronavirus pandemic crashed asset prices and hurt risk sentiment. 

"It seems like everything is going their way right now. It's just strength across the entire platform," said Kyle Sanders, an analyst with St. Louis-based financial services firm Edward Jones. 

Despite the better-than-expected results, BlackRock shares fell by 3.3 percent to $877.98, a near one week low. 

Investors may have been disappointed in net inflows coming in at $81 billion, down from $172 billion in the prior quarter, a drop associated with the loss of a $58 billion equity index mandate from a U.S. pension fund client, analysts said. 

"People are also focused on where the growth is coming, and the growth is coming in the ETF business, which tends to generate a lower revenue base than the traditional long only asset management business," said CFRA Research analyst Cathy Seifert. 

A combination of these factors may have spooked investors, Seifert, who still likes the stock and would treat Wednesday's weakness as a buying opportunity, said.

BlackRock remains well placed to be a leader in the asset management industry, analysts said.

"Despite them having $9.5 trillion and being so big, they are still best positioned to deliver the best growth over the next couple of years, relative to their peers," Sanders said.

The company's adjusted net income rose to $1.55 billion, or $10.03 per share, in the three months ended June 30, from $1.21 billion, or $7.85 per share, a year earlier.

Analysts on average had expected a profit of $9.46 per share, according to IBES data from Refinitiv.

Revenue rose by 32 percent to $4.82 billion, helped by higher performance fees and 14 percent growth in revenue from technology services.

BlackRock's shares rose 16 percent during the quarter ended June 30, compared with a 15-percent gain for a Thomson Reuters index that includes more than a dozen of BlackRock's industry rivals in the United States.
