BlackRock, Inc. (BLK) closed at $1,058.92 on September 16, 2026, declining 0.65% over the prior 24-hour period. The move added to a broader stretch of weakness for the asset management giant.
Over the past seven days, shares have fallen 3.37%, while the 30-day decline stands at 9.80%, reflecting sustained selling pressure over the past month. The stock's market capitalization sits at $165.03 billion.
The cumulative pullback over the 30-day window marks a notable retreat from higher levels, with losses deepening across each measured timeframe. The session's modest single-day drop follows a steeper weekly decline, suggesting the pace of selling has moderated in recent days.
BlackRock remains one of the world's largest asset managers by market capitalization, though the recent price action has weighed on its overall valuation through the measured period.
