Taiwan Monthly Revenue — YoY, MoM and momentum, disclosure-date stamped
Monthly revenue is Taiwan's unique high-frequency fundamental: few markets require listed companies to report sales every month. We structure the filings into YoY, MoM and momentum series, each row stamped with its official disclosure date.
Why disclosure stamps matter
Filings are due by the 10th of the following month, but actual dates vary by company and month. Aligning backtests by calendar month assumes you knew the number on day one — classic lookahead bias. Every row carries its actual disclosure date, so signals only activate after publication.
What we deliberately do not do
We do not forecast revenue or run 'revenue-momentum screens'. Monthly revenue is a top-line shipment figure: it excludes margin, opex and FX, and above all excludes expectations — a surge that undershoots consensus can move the price the other way.
We also do not rank momentum across companies: seasonality differs enormously by industry, so a shared leaderboard compares two different things.
