TransAlta Corporation Stock: price and insider trades · Canada

TransAlta Corporation is a listed company. Filings by its managers are published through SEDI. The last twelve months, up to 18 October 2026, brought 129 filings signed by 15 insiders.

Not one open-market sale was filed. On the buying side, 2 insiders reported 7 purchases totalling €400k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Among those who bought: 2 senior executives. The largest single trade was a purchase of €120k by Politeski, Michael, published on 22 June 2026, equal to 0.0036% of the market capitalisation.

The clock since the last published purchase (16 September 2026) now reads 31 days. The median gap between a trade and its publication by SEDI is 1 day. That lag is the time during which only the insider knows about the trade.

For context, the typical company on the same exchange (median of 2,121 companies) published 11 filings over the same period, against 129 filings here. The full history, which starts in 2026, counts 7 purchases against no sales.

This summary is built from SEDI disclosures alone and does not predict where the share price will go.
