WisdomTree Investments, an ETF sponsor and asset manager, reported net income of $7.9 million for the first quarter of 2013, up seven times from the year ago quarter and 50% from the fourth quarter of 2012.

WisdomTree CEO and President Jonathan Steinberg commented, "WisdomTree's net inflows of $5.9 billion represented our best quarter yet and fueled a meaningful acceleration in our organic growth in 2013.”

The company’s currency hedged Japanese equity strategy “led the entire ETF industry with $3.9 billion of net inflows in the first quarter,” Steinberg said in a release. WisdomTree is also “seeing balanced growth across our platform in important asset classes,” he said. “In fact, excluding Japan-related assets, we achieved our second best quarter with $1.9 billion in inflows across our dividend-weighted equity and fixed income strategies."

WisdomTree has $27 billion in assets and is the fifth largest U.S. ETF sponsor.
