CSI: what insiders have been doing
CSI, classified in the Industrials sector, is a listed company. Its insiders report their share dealings to TWSE / TPEx (MOPS). From 22 October 2025 to 22 October 2026, the disclosure feed for CSI logged 4 filings by 4 insiders.
Not one of the filings records a straightforward purchase or sale on the market. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.
No insider has bought CSI shares on the open market in the past twelve months. Publication is fast: at least half of the trades appear on TWSE / TPEx (MOPS) on the same day. That lag is the time during which only the insider knows about the trade.
With 4 filings in twelve months, the company is more active than the median of 2 filings across the 620 companies we follow on the same exchange.
These figures are compiled from regulatory filings published by TWSE / TPEx (MOPS). They describe what insiders did and are not a recommendation.
Transparent value + quality ranking, distinct from the insider signal.
