description: "Marking this down. On the last day of March, witnessed a "Tracy McGrady moment." The first time US stocks gained over 10% in a single day.However, it's nothing to be proud of, because margin was used, which is wrong and strongly opposed by both Da Dao and Buffett. The reason is that the initial buying point was too early, and when good opportunities later arose, margin had to be used, which was actually a mistake. After US stocks have a decent rebound, will sell some shares to cover the margin.The situation remains unclear. As Buffett said, the moment of "value for money" has not yet arrived. Proceed with caution and cherish every opportunity to act.$NASDAQ Composite Index(.IXIC.US)$S&P 500(.SPX.US)"
