BlackRock Inc. (NYSE:BLK) is shifting its stance from promoting index investing to advocating for actively managed strategies, citing the current economic environment of higher interest rates, persistent inflation, and geopolitical risks as more conducive for active management. This marks a significant departure from the buy-and-hold strategy that has been popular among investors, driven by a decade of low interest rates and strong performance of developed-market stocks and bonds. BlackRock analysts argue that the traditional approach of static asset allocations will not be as effective, urging investors to adopt more dynamic strategies.
