Prepare an A-share quarter bridge for S01
Before asking S01 to explain quarterly changes, determine which values are actually quarter-only. A “third-quarter report” can contain both third-quarter and year-to-date columns; the document title does not define every row.
Build the bridge
This self-authored example assumes matching consolidated revenue in RMB millions.
| Window | Current | Prior | Interpretation |
|---|---|---|---|
| January–June | 700 | 650 | Cumulative flow |
| January–September | 1,120 | 1,000 | Cumulative flow |
| July–September | 420 | 350 | Derived by subtraction |
| Quarter growth | 20% | — | 420/350−1 |
| Nine-month growth | 12% | — | 1120/1000−1 |
Preserve original cumulative rows alongside the derived quarter. A derived value needs two references, not a fabricated page citation. If the earlier report was restated, determine whether both operands use the same basis.
Source preparation
Locate real documents through SSE disclosures or the appropriate exchange. Record identity, report title, covered dates, unit, scope, disclosure date and version. Our mainland source guide explains the manual workflow and rights boundary; opening the exchange page is not a tested data connection.
Use a bridge file with columns for metric, period start/end, scope, currency, scale, source location, original value and calculation. Keep statement balances separate: September and June receivables may be differenced to analyze change, but that is not a quarter-only revenue-like flow.
Ask S01 to verify before explaining
Prompt: “Read the period bridge and originals. Check each subtraction for matching scope and versions, then compare quarter and cumulative changes separately. Do not annualize, silently replace comparatives or infer causes from the growth rate.”
If only the nine-month file exists, request the missing half-year basis rather than assuming an earlier number. If the issuer changed fiscal year, consolidation or accounting treatment, ordinary subtraction may not represent comparable operations.
Review the conclusion
In the synthetic example, quarter growth exceeds cumulative growth. That observation alone does not prove accelerating organic demand: acquisition, pricing, mix and base effects remain possible. The next check is notes and the comparable cash-flow window.
Limitations
This bridge is arithmetic and document discipline, not a complete A-share database or an accounting opinion. Do not upload restricted reports to a provider without permission. Free methods do not grant redistribution rights to source documents.
FAQ
Can I derive a quarter from two differently restated reports?
Not until their bases are reconciled.
Do I subtract balance-sheet amounts the same way?
Their difference is a balance change, not a quarter flow of the same type as revenue.
