Group 1 - The core viewpoint of the article is that the A-share market is not driven by news but by preemptive actions taken by institutions, leading to a calm response to significant news like the new tariff policy announced by the U.S. [1][2] - The article highlights the lagging nature of news and how the A-share market operates on anticipatory trading, resulting in retail investors often buying at peak prices when good news is finally announced [2][3] - It emphasizes that understanding real trading behaviors through data can help investors avoid being misled by news [2][3] Group 2 - The first case discussed is about the "trap" of mid-year earnings forecasts, where stocks like "Shengtun Mining" and "Qifeng New Materials" show differing performances despite both announcing earnings increases [3][5] - The article explains that the market is not merely reacting to concepts like earnings growth but is influenced by institutional pricing power, which can lead to significant price movements [5][7] - It points out that when institutional funds are active, stock prices tend to rise, while inactivity can lead to declines, as seen in the contrasting performances of the two mentioned stocks [7] Group 3 - The second case involves the "black swan" event affecting liquor stocks due to a sudden "liquor ban," which caused a significant drop in stock prices [8][10] - The article argues that the decline was not unexpected, as institutional sentiment had already shifted prior to the announcement, indicating that market movements are often predictable based on institutional behavior [10][12] - It concludes that the lack of institutional participation in the liquor sector's rebounds was a clear sign of their negative outlook, contradicting the notion of a "black swan" event [12] Group 4 - The article calls for retail investors to focus on real trading behaviors and quantitative data to understand market dynamics better and avoid being "cut as leeks" by institutional players [13] - It reiterates that the calmness of the A-share market in response to the tariff news is a result of prior institutional actions, underscoring the importance of tracking institutional trading activity [13]
