- The report introduces a timing radar model based on six dimensions, including liquidity, economic conditions, valuation, capital flow, technical signals, and crowding metrics, to generate a comprehensive timing score ranging from [-1,1][2][7][9] - Liquidity factors include "monetary direction" and "monetary strength" indicators. The monetary direction factor is calculated using central bank policy rates and short-term market rates, comparing their average changes over the past 90 days. If the factor > 0, it indicates monetary easing. The monetary strength factor is derived from the deviation of DR007 relative to the 7-year reverse repo rate, smoothed and standardized using z-score. If the factor < -1.5 standard deviations, it signals a future easing environment[11][15][16] - Credit factors include "credit direction" and "credit strength" indicators. The credit direction factor is calculated using monthly long-term loan data, analyzing the past 12-month increment and year-over-year changes. If the factor rises compared to three months ago, it signals a positive trend. The credit strength factor measures deviations in new RMB loans relative to expectations, standardized using z-score. If the factor > 1.5 standard deviations, it indicates a significant credit surprise[18][22][24] - Economic factors include "growth direction" and "growth strength" indicators. The growth direction factor is based on PMI data, calculating the 12-month average and year-over-year changes. If the factor rises compared to three months ago, it signals a positive trend. The growth strength factor measures deviations in PMI relative to expectations, standardized using z-score. If the factor > 1.5 standard deviations, it indicates significant growth surprises[25][28][30] - Inflation factors include "inflation direction" and "inflation strength" indicators. The inflation direction factor combines CPI and PPI data, calculating a weighted average and comparing changes over three months. If the factor decreases, it signals a favorable environment for monetary easing. The inflation strength factor measures deviations in CPI and PPI relative to expectations, standardized using z-score. If the factor < -1.5 standard deviations, it indicates significant inflation surprises[32][35][36] - Valuation factors include "Shiller ERP," "PB," and "AIAE" indicators. Shiller ERP is calculated using inflation-adjusted earnings over six years, subtracting the 10-year government bond yield, and standardized using z-score. PB is processed similarly, with a 1.5 standard deviation truncation. AIAE measures equity allocation proportion, calculated as total market capitalization divided by the sum of market capitalization and total debt, standardized using z-score[38][40][44] - Capital flow factors include "margin financing increment" and "trading volume trend" for domestic capital, and "China sovereign CDS spread" and "overseas risk aversion index" for foreign capital. Margin financing increment compares the 120-day average increment to the 240-day average increment. CDS spread measures the 20-day difference in smoothed CDS levels, while the risk aversion index uses Citi RAI data to assess overseas sentiment[47][53][56] - Technical factors include "price trend" and "new highs and lows." Price trend uses moving average distances (ma120/ma240-1) to assess market direction and strength. New highs and lows measure the difference between the number of new highs and lows among index constituents, smoothed over 20 days[60][63][64] - Crowding metrics include "option implied premium," "VIX," "SKEW," and "convertible bond pricing deviation." Option implied premium and VIX assess market sentiment based on recent returns and percentile rankings. SKEW measures the implied skewness of options, while convertible bond pricing deviation calculates the deviation of bond prices from model estimates, standardized using z-score[66][72][74] - Current scores for key factors: monetary direction (1), monetary strength (-1), credit direction (1), credit strength (0), growth direction (1), growth strength (-1), inflation direction (-1), inflation strength (0), Shiller ERP (0.07), PB (-0.46), AIAE (-0.77), margin financing increment (1), trading volume trend (0), CDS spread (1), risk aversion index (-1), price trend (0), new highs and lows (-1), option implied premium (-1), VIX (-1), SKEW (-1), convertible bond pricing deviation (-1)[12][19][26][29][42][43][45][48][50][54][57][62][65][68][72][75]

- The report mentions the construction of A-share sentiment index based on market volatility and transaction volume changes, dividing the market into four quadrants. Only the quadrant with "volatility up - transaction down" shows significant negative returns, while others show positive returns. This sentiment index includes bottom warning and top warning signals[36][39][42] - The A-share sentiment index currently indicates bearish signals for both bottom warning (price) and top warning (volume), resulting in an overall bearish outlook for the market[39][42] - The A-share prosperity index is constructed using the YoY growth of net profit attributable to the parent company of the Shanghai Composite Index as the Nowcasting target. The index shows a slow upward trend, indicating the current upward cycle[29][33][35] - The prosperity index value as of September 19, 2025, is 21.21, which has increased by 15.79 compared to the end of 2023, confirming the upward cycle[33][35] - The report applies the BARRA factor model to construct ten major style factors for the A-share market, including SIZE, BETA, MOM, RESVOL, NLSIZE, BTOP, LIQUIDITY, EARNINGS_YIELD, GROWTH, and LVRG[57][58][60] - Among style factors, BETA factor shows high excess returns, while RESVOL factor demonstrates significant negative excess returns. High BETA and high growth stocks perform well, whereas non-linear size and value factors underperform[58][59][61] - The report analyzes the performance attribution of major indices using factor models. Indices like CSI 500, ChiNext Index, and Wind All A exhibit strong exposure to BETA factor, leading to favorable performance in style factors. Conversely, indices like Shanghai Composite Index and SSE 50 show weaker exposure to BETA factor, resulting in poor performance in style factors[66][67][73] - The CSI 500 enhanced portfolio has generated a cumulative excess return of 48.55% relative to the CSI 500 index since 2020, with a maximum drawdown of -5.73%. However, its weekly performance is -0.24%, underperforming the benchmark by 0.56%[45][47][49] - The SSE 300 enhanced portfolio has achieved a cumulative excess return of 38.48% relative to the SSE 300 index since 2020, with a maximum drawdown of -5.86%.

- The timing radar six-dimensional model is constructed based on multiple dimensions including liquidity, economic fundamentals, valuation, capital flow, technical signals, and crowding indicators, with 21 metrics categorized into four major groups: "valuation cost-effectiveness," "macro fundamentals," "capital & trend," and "crowding & reversal" to generate a comprehensive timing score ranging from [-1,1][1][6][8] - Liquidity dimension includes factors such as monetary direction, monetary strength, credit direction, and credit strength. For example, the monetary direction factor is calculated using the average change in central bank policy rates and short-term market rates over the past 90 days. If the factor is greater than 0, it indicates a loose monetary policy environment[12][15][17] - Economic dimension includes growth direction, growth strength, inflation direction, and inflation strength factors. For instance, the growth direction factor is derived from PMI data, calculating the 12-month average and year-over-year change. If the factor shows an upward trend compared to three months ago, it signals a positive outlook[24][27][31] - Valuation dimension includes metrics such as Shiller ERP, PB, and AIAE. For example, Shiller ERP is calculated as $1/Shiller PE - 10-year government bond yield$, with a z-score based on the past six years' data[36][38][42] - Capital flow dimension is divided into domestic and foreign capital metrics. Domestic metrics include margin trading increment and turnover trend, while foreign metrics include China's sovereign CDS spread and overseas risk aversion index. For instance, the CDS spread factor signals foreign capital inflow when the 20-day differential is less than 0[45][52][55] - Technical dimension includes price trend and new highs/lows metrics. For example, the price trend factor is calculated using the moving average distance $(ma120/ma240-1)$, with scores determined by the trend direction and strength[58][61][63] - Crowding dimension includes derivative signals such as implied premium, VIX, SKEW, and convertible bond pricing deviation. For instance, the implied premium factor is derived from the 50ETF's 5-day return and percentile ranking, signaling market crowding levels[64][65][70] - Current scores for the six dimensions are as follows: liquidity 0.25, economic fundamentals -0.25, valuation -0.40, capital flow 0.00, technical signals -0.50, and crowding 0.00, resulting in a comprehensive timing score of -0.15[7][8][10]

Group 1 - The core viewpoint of the article emphasizes skepticism towards reports of continuous capital inflow into stocks, suggesting that such information may be misleading and that true opportunities often lie hidden [1][3]. - Historical patterns in the stock market indicate that significant capital inflow data can lead to poor investment decisions, as seen in the 2015 market situation where retail investors were left holding losses [3][4]. - The article warns that the information available to investors is often curated to present a specific narrative, similar to a magician's trick, where the real action is concealed [4][10]. Group 2 - The article highlights the importance of quantitative data over visual market indicators, suggesting that true market behavior is revealed through data analysis rather than superficial price movements [10][12]. - It points out that while Yunnan Energy Investment has seen continuous net capital inflow for 17 days, this does not necessarily indicate the stock's quality but rather the presence of large institutional trading [12]. - The discussion of the 124 stocks with continuous net capital inflow serves as a reminder that appearances can be deceiving, and investors should be cautious of potential traps hidden behind seemingly positive data [12].

Sou Hu Cai Jing· 2025-09-07 12:14
Group 1 - The core viewpoint is that the shift in the Federal Reserve's stance reflects a broader trend of market manipulation and expectation management, similar to the behavior observed in the A-share market [1][3] - The article highlights that market movements are often driven by unseen "puppet masters" rather than the apparent news and data, suggesting that retail investors are misled by surface-level information [3][4] - It emphasizes the importance of understanding institutional trading behaviors, which can create opportunities for profit despite market volatility [4][10] Group 2 - The concept of "institutional shaking" is introduced, where institutions deliberately create market fluctuations to accumulate shares, which may appear as random volatility to retail investors [8][11] - The article suggests that recognizing these institutional behaviors can provide insights into market trends and help investors navigate through market turbulence [11][13] - It concludes that both the Federal Reserve's communication and institutional trading practices serve the purpose of managing market expectations, urging investors to look beyond superficial market movements [11][13]
