According to TechFlow news on December 18, as reported by Jinshi, BlackRock stated in a report that government bonds are no longer a reliable buffer against the sell-off of risk assets such as stocks. Investors should consider using gold and Bitcoin as a complement to bond investments. Economies are undergoing a transformation that may continue to alter long-term economic trends. In the context of rising inflation, bonds may not be able to withstand a sell-off in the stock market. Bonds no longer reliably diversify the risk of a portfolio across a wide range of potential outcomes and scenarios. This necessitates a reconsideration of diversification. Therefore, investors should consider new diversification investment tools such as gold and Bitcoin, even though they will not replace bonds.
