A single-period RPS ranking is only a cross-sectional photo; what truly has judgmental value is how the outputs of the same calculation process change at different time points. This page extracts the market-level statistics from the weekly report archive period by period and lists them side by side for comparison, allowing the changes in the number of strong stocks, the scale of valid samples, and the trajectory of leading industries to be directly observed and verified. All figures are directly taken from the respective weekly report pages without secondary processing.
The table below lists, for each period's weekly report, the number of valid samples in the four markets, the number and proportion of targets with RPS above 90 points, and the industry that appears most frequently among the top 50 ranked securities.Please note the period field: Statistical data from different periods cannot be directly compared.
| Snapshot Date | Period | Market | Effective Sample | RPS≥90 | Proportion | Top 50 Leading Industry |
|---|---|---|---|---|---|---|
| 2026-08-15 | RPS50 | China A-shares | 5,212 | 523 | 10.0% | Pharmaceuticals and Biotechnology (18) |
| 2026-08-15 | RPS50 | Hong Kong stocks | 2,752 | 277 | 10.1% | Industrials (13) |
| 2026-08-15 | RPS50 | US stocks | 8,737 | 875 | 10.0% | Consumer Discretionary (14) |
| 2026-08-15 | RPS50 | Japanese stocks | 3,706 | 371 | 10.0% | Information and Communications (12) |
| 2026-08-17 | RPS50 | China A-shares | 5,212 | 522 | 10.0% | Pharmaceuticals and Biotechnology (17) |
| 2026-08-17 | RPS50 | Hong Kong stocks | 2,752 | 280 | 10.2% | Industrials · Construction (9) |

| 2026-08-17 | RPS50 | Japanese stocks | 3,707 | 371 | 10.0% | Information and Communications (13) |
| Market | Top 50 Leading Industries (by Snapshot Date) |
|---|---|
| China A-shares | Pharmaceutical and Biotech(08-15 · RPS50) → Pharmaceuticals and Biotechnology(08-17 · RPS50) |
| Hong Kong stocks | Industrials(08-15 · RPS50) → Industrials · Construction(08-17 · RPS50) |
| US stocks | Consumer Discretionary(08-15 · RPS50) → Consumer Discretionary(08-17 · RPS50) |
| Japanese stocks | Information and Communication Industry(08-15 · RPS50) → Information and Communications(08-17 · RPS50) |
Under this consistent RPS50 methodology, A-shares were led by Pharmaceuticals & Biotechnology for two consecutive periods, U.S. stocks by Consumer Discretionary for two consecutive periods, and Japanese stocks by Information & Communications for two consecutive periods. Only such repeated appearances across periods have value for rotation analysis; industries appearing in only a single period are more likely to reflect short-term fluctuations. To place industry distribution within a systematic framework, see Industry Rotation Analysis。
Looking at the table above you can see a stabilization: four markets, two snapshot dates, the same RPS50 cycle,The proportion of targets with RPS above 90 points falls within the extremely narrow range of 10.0% to 10.2%.It's not a coincidence.It is the mathematical necessity of the percentile ranking - RPS is defined as the percentage of the cross-sectional return of a stock in its market,In theory, about 10% samples will fall above 90.
This property has two implications. First, it is aself-check metric for the calculation process: if the proportion in a given period materially deviates from 10%, it typically indicates an anomaly in sample screening or ranking logic rather than a change in market conditions. Second, it reminds usersnot to judge market strength or weakness by the number of high-scoring stocks—in both bull and bear markets, 10% of stocks will rank in the top 10%. Overall market conditions should be judged by absolute returns, industry concentration and cross-market comparisons; for the specific methodology, see RPS Calculation Methodology。
A valid sample is the number of securities that have complete historical data for the current period and are able to calculate the RPS value for the period.Between 2026-08-15 and 2026-08-17 snapshots that are RPS50,A-shares maintain 5,212, HK-shares maintain 2,752, US-shares maintain 8,737,Japanese stocks were added from 3,706 to 3,707.This small change mainly reflects the availability of data in the current period.It should not be interpreted as an overall expansion or contraction of the market.Coverage and data retrospectives for each market can be found at Four-Market Data Coverage Notes。
This page uses only two weekly reports, 2026-08-15 and 2026-08-17, with structured, citable conclusions and the same RPS50 caliber.Additional historical and upcoming weekly reports can be found in the archive directory.

RPS is the percentile rank,Samples with 10% by definition will fall above 90.The proportion of the four markets in the actual two-phase data is distributed between 10.0% and 10.2%.This means that there is no systematic offset in the calculation process.rather than a consistent strength in the market.Judging the strength of the market should look at the absolute ups and downs and the concentration of the industry.rather than looking at the proportion of high dividend stocks.
If the same industry appears repeatedly on the leaderboard across consecutive periods with the same lookback, it indicates a degree of persistence in that industry’s relative strength. A-shares being led by Pharmaceuticals & Biotechnology for two consecutive periods under the RPS50 methodology, and U.S. stocks by Consumer Discretionary for two consecutive periods, are examples of this. Industries appearing in only a single period are more likely to result from short-term fluctuations or small-sample effects.
A valid sample is a security that has complete historical data for the current period and can calculate the RPS value for the period.Between 2026-08-15 and 2026-08-17 snapshots that are RPS50,The sample size of A-shares, HK-shares and US-shares remained unchanged.Japanese shares increased from 3,706 to 3,707;These minor changes mainly reflect current data availability.
Yes, but we recommend also noting the snapshot date, lookback and sample size, for example “RPS Stock, 2026-08-17 snapshot, A-share effective sample 5,212 names.” For the full citation format and machine-readable distribution, see the public data directory. All figures are current-period cross-sectional statistics and contain no forecasts of future returns.
