BlackRock stated in a recent publication that the performance of the US stock market is concentrated in the technology sector and is dominated by the theme of artificial intelligence, not a market flaw. From a tactical perspective, they hold a bullish view on US stocks for the next 6 to 12 months, and prefer opportunities related to the theme of artificial intelligence. As the profits of the US stock market expand, they also see investment opportunities in the medical and industrial fields. Due to the good profitability of technology companies' financial reports, BlackRock is less concerned about valuation indicators. The free cash flow of these technology companies is almost twice the proportion of total market sales revenue and has the highest profit margin in various industries. In addition, many top technology companies are profitable and have sufficient cash to provide funds for the construction of data centers and other artificial intelligence infrastructure. In the past few weeks, as the European stock market has fallen, investors who prefer high-quality stocks may flock to the US stock market.
