Purchases make up the whole of the open-market record (37 purchases, €1.1M). Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. 2026 to date brings 4 purchases and no sales.

Half of the purchases are above €1,226 and half below. Measured against the company's value, the median purchase equals 0.0000% of market capitalisation, across 4 purchases where it is known. Clusters matter here: 29 out of 36 purchases overlapped with buying by a colleague within 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

On 30 September 2026 came the latest disclosure, an open-market purchase for €21k in Anglo American plc. Filings reach the RNS (LSE) feed a median of 1 day after the trade. For comparison, UK MAR gives managers three business days to notify a trade. Source: insider filings from RNS (LSE). Past trades are no guide to future returns.
