Glenbrook Capital Management

All filings by Glenbrook Capital Management on record concern SenesTech, Inc. The record holds 27 filings, for trades running from 30 January 2026 to 22 October 2026.

The open-market record is one-sided, with 27 purchases worth €1.4M and not one sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price.

In size, the median ticket on the buying side is €17k. Measured against the company's value, the median purchase equals 1.2% of market capitalisation, across 7 purchases where it is known. Of 24 purchases, 9 formed part of a group of insiders buying within 30 days of each other. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. Ninety days after publication, 18 purchases show a median change of -24.5%, with the price up in 0% of them. They describe history only and say nothing certain about the share price ahead.

The latest filing, published on 22 October 2026, reports an open-market purchase of €22k in SenesTech, Inc. 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. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
