BlackRock's stock is having its best day in more than a year as money pours into the active management of assets, which is more profitable than index investing

BlackRock CEO Larry Fink, shown here at the BlackRock Infrastructure Summit on March 11, 2026, in Washington, D.C., said Wednesday that the firm's assets under management have risen to a record $15.3 trillion.

Shares of BlackRock were rallying toward their best day in more than a year on Wednesday, after strong inflows into exchange-traded funds and buoyant markets helped the world's biggest asset manager beat Wall Street's earnings expectations for the latest quarter.

Investment inflows during the first half of the year were more than double those of a year ago, "representing the strongest start to our year in our history," BlackRock Chair and CEO Laurence Fink said on the post-earnings call with analysts, according to a FactSet transcript.
