U.S. pensions' $30 billion rebalancing selling pressure enters its final day. The mid-year asset rebalancing operations of major U.S. pension plans enter their final execution day today, with the market estimating about $15 billion to $20 billion in passive U.S. stock selling pressure yet to be unleashed. As U.S. equities significantly outperformed fixed-income assets in the first half of the year, pension stock allocations are severely overweight, making AI and tech growth stocks the primary targets for reduction. Traders warn of potential concentrated selling late in the session today, which could heighten intraday volatility.

Corning's surge and Rocket Lab's massive acquisition became the two most eye-catching themes in overnight US stocks, reflecting an accelerating rotation of capital from core AI chips to 'second-tier supply chain' sectors such as infrastructure materials and space communications. Meanwhile, pension rebalancing selling pressure has entered its final stretch, with the AI semiconductor sector remaining the hardest-hit area for selling. Tonight's post-market earnings from Nike and the Conference Board Consumer Confidence Index will provide the market with the latest clues on the consumer front. Nike's stock price is currently near a 12-year low, and whether its earnings can beat expectations will directly impact sentiment in the consumer sector. If economic data beats expectations, it may further reinforce Fed tightening expectations; if the data is weak, it is expected to provide some breathing room for the quarter-end market.
