BlackRock (NYSE: BLK) shares climbed 1.1% to $1,105.12 during late morning trading on the New York Stock Exchange, extending a 6.6% gain following the company's second-quarter earnings report on Wednesday. The S&P 500 edged lower as investors focused on fee income growth rather than the record $15.34 trillion in assets under management (AUM) the firm reported at the end of June.
Market Gains Drive AUM Growth
Preliminary data indicate that market appreciation contributed approximately $1.284 trillion of the $1.45 trillion increase in AUM during the second quarter, accounting for roughly 89% of the total growth. Net inflows added about 13%, while currency fluctuations and investment sales partially offset the gain. The more notable metric was organic base-fee growth of 8%, underscoring the firm's ability to generate revenue from its asset base.
Active Strategies Outperform in Fee Generation
Active investment strategies, which represent 24% of total AUM, generated 42% of base-fee and lending revenue. In contrast, non-ETF index mandates, comprising 28% of AUM, contributed only 7% of such revenue. This disparity highlights the higher fee margins associated with active management. Early estimates suggest that active assets generate roughly seven times the fee revenue per dollar compared to non-ETF index assets.
Net Flows by Investment Style
- Active: $53.3 billion in net inflows, representing 24% of AUM and 42% of base-fee and lending revenue.
- ETFs: $177.9 billion in net inflows, representing 41% of AUM and 45% of base-fee and lending revenue.
- Non-ETF Index: $32.1 billion in net outflows, representing 28% of AUM and 7% of base-fee and lending revenue.
ETFs continued to dominate trading volumes, attracting $177.9 billion in net inflows, which accounted for roughly 93% of total net inflows. BlackRock ended June with $6.25 trillion in ETF assets. The scale of outflows from non-ETF index funds likely had a muted impact on fees given their lower revenue contribution per dollar.
Private Markets and Earnings Beat
Private markets added $15.4 billion in net inflows, representing 2% of AUM but contributing 11% of base-fee and lending revenue. The HPS acquisition added approximately $230 million in fees during the quarter. Adjusted earnings came in at $13.91 per share, surpassing the $12.59 average analyst estimate. Revenue rose 31% to $7.08 billion, and the adjusted margin reached 45.9%, the highest level in nearly five years.
CEO Larry Fink noted that "demand is building across our active franchise," and the firm increased its 2026 share buyback target to $2 billion, up from $1.8 billion.
Risks and Outlook
While the stock has risen for two consecutive days, reflecting growing investor confidence in earnings, risks remain. A market downturn could erode asset values and fee income. Slowing demand for active strategies or pressure on high-margin private credit bets could also weigh on performance. The sustainability of active and private market inflows will be a key focus for investors going forward.
