Group 1 - The core viewpoint is that the A-share market is heavily influenced by external news, leading to erratic stock price movements, which can be likened to a "puppet show" controlled by information [1] - The Federal Reserve's decision to maintain interest rates is seen as a significant factor affecting market sentiment, with the dot plot indicating a lack of imminent rate cuts, which could lead to prolonged market uncertainty [2][3] - There is a growing concern regarding the credibility of the US dollar, as international capital begins to lose faith in it due to the weaponization of the dollar settlement system [3][5] Group 2 - The market's reaction to the Federal Reserve's decision illustrates the characteristics of an "external leverage market," where neutral news is exaggerated in a fragile market environment, leading to significant volatility [6] - Retail investors often fall into the trap of emotional trading, reacting to short-term market movements rather than focusing on underlying data, which contributes to their losses [9] - The use of quantitative analysis tools has revealed the importance of understanding institutional trading activity, particularly through "institutional inventory" data, which reflects the true market dynamics [10][12] Group 3 - Observations of specific stocks demonstrate that price movements can be misleading; a stock that experiences a rapid rise may not have institutional support, while a stock that declines may have strong institutional backing, leading to a rebound [12][14] - The ability to visualize data and analyze institutional inventory alongside price charts can provide clearer insights into market trends, moving beyond superficial analysis [14][17] - The focus on interest rate expectations may obscure deeper funding trends, highlighting the need for investors to identify hidden opportunities within the market [15]

Group 1 - The core point of the article is that the recent U.S. CPI data for May came in lower than expected, leading to increased market speculation about potential interest rate cuts by the Federal Reserve [2][5] - The U.S. CPI year-on-year rate was reported at 2.4%, below the expected 2.5%, while the core CPI increased by 2.8%, also lower than the anticipated 2.9% [2][6] - Following the CPI release, the probability of a rate cut in September surged to 70%, with expectations for at least two cuts within the year [5] Group 2 - Despite the excitement in the market, the probability of a rate cut in June is only 2.4%, indicating that significant actions may still be months away [6] - The article discusses that a decrease in inflation suggests a potential economic slowdown, prompting the Federal Reserve to consider lowering interest rates to stimulate the economy [7] - It highlights that institutional investors typically do not wait for favorable conditions but instead leverage market expectations to position themselves, often causing market volatility before actual rate cuts occur [8][10] Group 3 - The article emphasizes the importance of understanding institutional trading behaviors rather than relying solely on market sentiment or technical analysis [10][12] - It provides examples of past stock movements, illustrating that significant price increases often follow periods of institutional accumulation, while lack of institutional support can lead to price declines [12][15] - The key takeaway is that recognizing and analyzing data related to institutional activity is crucial for making informed investment decisions [15][17]
