BlackRock Investment Institute upgraded short-term U.S. Treasuries to overweight and long-term U.S. Treasuries from underweight to neutral, ending its nearly six-year underweight strategy on U.S. Treasuries. Concurrently, the institution downgraded U.S. equities and U.S. agency mortgage-backed securities (MBS) from overweight to neutral, aiming to lock in attractive current Treasury yields and manage recent risks in U.S. equities.
