Altek: what insiders have been doing
Altek is a listed company. Its directors and officers file their transactions with TWSE / TPEx (MOPS). The last twelve months, up to 18 October 2026, brought 6 filings signed by 6 insiders.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.
With 6 filings in twelve months, the company is more active than the median of 2 filings across the 515 companies we follow on the same exchange.
No insider has bought Altek 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.
Source: insider filings from TWSE / TPEx (MOPS). Past trades are no guide to future returns.
