$Roundhill Memory ETF(DRAM.US)open ai sales fell short of expectations. In this pre-market session, Micron and DRAM stocks saw a significant drop. In the short term, there is a clear component of emotional overselling and being mistakenly dragged down by the beta of the AI sector. However, the future inflation expectations driven by rising oil prices and the interest rate hike expectations from the Bank of Japan and the Federal Reserve remain a Damocles' sword hanging overhead. Those with heavy positions may consider appropriately reducing holdings after 40, as there is still room for growth at present.
