This breakdown is generated from the filed numbers and sub-scores above — no outside narrative, no estimates. Where a filing doesn’t disclose an input, the sentence that would need it is omitted instead of guessed.
Not disclosed in LDDD’s filings for these years — we don’t estimate it.
Gaps in a line mean that item isn’t in LDDD’s filings for that year — the series is never interpolated or estimated. The Table view lists every filed value, including operating and net margins, total debt, and share count.

Track record
How LONGDUODUO COMPANY LIMITED’s moat rated in each of the years we can reconstruct from its filings — scored only on what was knowable at the time — and what its price and returns did afterward. The score never saw a price; the two are joined only in hindsight, for education, not as a signal.
How to read this: each dot is what the engine would have scored LDDD on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.
Two tracks, one timeline: the score has its own 0–100 scale (top), the price its own 100-based scale (bottom) — never a shared axis. The price path is a total-return (dividends reinvested) index built from the same data the forward returns use; gaps in the score line are years with no reconstructed rating (see the table for why). The Table view carries every value.
What followed, in the years it rated Wide
In the reconstructed history shown, LDDD did not rate Wide-moat in any year, so there is no wide-moat track record to report. That absence is itself the honest answer — we don’t manufacture a comparison where the rating never earned one.
