Never Forget the Ancestral Teachings

English summary

### Never Forget the Ancestral Teachings Time: 2026-07-31 22:06:56 Content: Never forget the ancestral teachings. The external market saw an epic surge, and it was expected to drive A-shares into a rebound, but the script is all too familiar. With good news in front of us, the market once again opened high and closed low. The warm breeze from outside failed to stabilize the market, and in the end, it was the intraday capital game that dragged itself down. The A-share ancestral teaching passed down by veteran traders is once again proven: when the market opens high on good news, priority should be given to taking profits, not blindly chasing highs. Today's tech hardware sector is the most direct reflection. Zhongji Innolight, Changxin Technology, GigaDevice, Eoptolink, and Cambricon surged sharply in early trading, then pulled back with volatility. Many stocks saw intraday drawdowns of nearly 10 points. Among them, Demingli's movement was the most representative: it hit the daily limit in early trading, but closed down 1%. The post-market Dragon-Tiger list clearly showed institutions dumping over 400 million yuan in a single day. A large number of memory and optical communication stocks, such as Longsys, Biwin Storage, Puran, Yuanjie, and Dongshan Precision, all showed similar patterns of rising then falling.
