5 insiders bought €189k of shares over the last 90 days, the latest filed 13 Aug 2026.
Headquartered in Melbourne, Australia, Starpharma Holdings Limited is a listed company and traces its origins to 1996. Filings by its managers are published through ASX. Over the twelve months to 18 October 2026, the company's managers filed 17 filings, from 9 insiders.
The record shows 5 purchases on the open market worth €189k, made by 5 insiders, against 1 sale by 1 insider. The totals do not cover 1 filing with an undisclosed amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Biggest ticket of the year: €122k, bought by Robert B. Thomas and made public on 13 August 2026 (0.057% of market cap). On the buying side, the filings list 5 senior executives among the declarants.
Within a 30-day window, 4 purchases overlapped with buying by a second insider. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. The last purchase on record was published on 13 August 2026, which is 66 days ago. Typically, a trade is published a median of 2 days after it takes place. The shorter that gap, the sooner other investors can see what insiders have done.
Compared with its exchange (2,222 companies, median 3 filings), a count of 17 filings is above the norm. The full history, which starts in 2026, counts 5 purchases against 1 sale.

This score ranks the purchase within its own market. A position size is suggested only on the venues of the backtested strategy universe; elsewhere, signals stay on watch. Not investment advice.
