BlackRock's Stock Falls 0.78% Amid 32.43% Volume Surge to $550M Ranks 258th in Trading Volume

On July 31, 2025, BlackRock (BLK) closed with a 0.78% decline, trading at $1,106.01. The stock saw a 32.43% surge in daily trading volume to $0.55 billion, ranking it 258th among active stocks. The move followed the firm’s expansion of its infrastructure investment offerings, which may influence long-term investor positioning.

BlackRock launched the iShares Infrastructure Active ETF (BILT), targeting the $68 trillion global infrastructure market by 2040. The actively managed fund aims to capitalize on growth in energy, logistics, and digital infrastructure sectors. With a 0.60% fee and a portfolio of 50–60 global infrastructure companies, BILT joins existing ETFs like IGF and IFRA, which collectively manage $10 billion. The firm’s broader infrastructure platform, Global Infrastructure Partners, oversees $183 billion across 100+ countries, underscoring its strategic focus on long-term asset allocation.

A backtested strategy of purchasing top 500 high-volume stocks daily and holding for one day generated a 166.71% return from 2022 to July 30, 2025. This outperformed the benchmark by 137.53%, driven by momentum in liquid stocks. The approach highlights the role of liquidity and timing in capturing market trends, though its efficacy may vary with evolving market dynamics.
