Material information filings by year

How many material-information filings Taiwan-listed companies published each year, grouped into classes — and how the mix shifted.

as_of: 2026-09-04
Sample period: 1993-01-05 → 2026-09-04
Rows: 304

Methodology

Filings are counted per year and per class. The class is NOT an official field: MOPS publishes only a ticker, a date, a time and a subject line, and the class here is TWMD's own rule set applied to that subject text. Nine classes are named and everything else folds into 「其他」, so each year carries at most nine rows plus the fold-up.

1993 onward, but not evenly. The endpoint flags 1993–1994 as sparse — under 5% of the median year — and that is DATA sparsity, not a market with no events, so comparing early years to recent ones will produce a wrong conclusion. The latest year is incomplete and its counts are naturally low. In the 「其他」 row, distinct tickers is a lower bound: the folded classes can share a company, and they are not double-counted.

What this means, and how to use it

Material information is what a listed company is required to disclose immediately, so the count is a rough measure of how eventful a year was — and the mix says what kind of eventful. A year heavy in 增資 and 私募 is a year of raising money; one heavy in 訴訟 or 停復牌 is a year of trouble. Read the classes as ours rather than as a regulator's taxonomy, and read the share rather than the raw count when comparing years of different completeness. History, not a forecast, and not investment advice.
