Willem Hendrik van Niekerk

Willem Hendrik van Niekerk discloses dealings in Tronox Holdings plc to SEC (Form 4). The record holds 40 filings, for trades running from 26 June 2012 to 10 February 2020.

Both buying and selling appear: 10 purchases worth €157k, against 1 sale worth €212k. On balance, insiders were net sellers of €55k. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Other entries cover 29 share grants.

In size, the median ticket on the buying side is €17k. Clusters matter here: 2 out of 3 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. After 10 purchases with a full 90-day history, the hit rate stands at 50% and the median 90-day move at -2.1%. Past outcomes like these are no guarantee of what comes next.

Most recently, on 12 February 2020, the filings show a share grant worth €23k in Tronox Holdings plc. The clock since the last published purchase (10 December 2018) now reads 2,891 days. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
