Yesterday, the rise of super-weight stocks led the Shanghai Composite Index to a new high, but there is suspicion of enticing more buyers, while the eight stocks were adjusted respectively. In the afternoon, the index changed, and both markets ended up with long bearish lines with great destructive power. The 5-day and 10-day moving averages were lost, and the volume was higher than the previous trading day. In view of the current market situation, it is necessary to remain cautious, which is specifically reflected in position control; if investors are still heavily weighted, they should take advantage of the opportunity of intraday rebound to continue reducing positions. At the same time, investors need to pay attention to the risk of structural adjustment in the market. For thematic varieties with huge increases, the main force has gained extremely rich profits. Even if the index falls limited in the future, the adjustment range of such individual stocks may still be large. The daily MACD indicator has already shown signs of turning into a green column. Therefore, investors who controlled their positions earlier should still remain on the sidelines in the short term, patiently waiting for the emergence of a rebound opportunity.
