CST Stock: price and insider trades · Taiwan

CST is a listed company. Filings by its managers are published through TWSE / TPEx (MOPS). The last twelve months, up to 18 October 2026, brought 12 filings signed by 4 insiders.

The filings describe grants, exercises and other transfers rather than trades on the open market. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

With 12 filings in twelve months, the company is more active than the median of 2 filings across the 517 companies we follow on the same exchange.

There has been no open-market purchase by an insider of CST for at least a year. The median gap between trade and publication is zero days: most filings appear on the same day. This delay matters because a trade only becomes useful information once it is public.

Every figure here comes from the filings published by TWSE / TPEx (MOPS) and describes the past, not future prices; it is not investment advice.
