Seth Lederman

All filings by Seth Lederman on record concern Tonix Pharmaceuticals Holding Corp., in the capacity of chief executive. We count 30 filings; the first trade dates from 23 March 2016 and the latest from 27 August 2026.

On the market, this insider has only ever bought: 29 purchases, €908k in total. No amount is published for 1 filing, which the totals therefore leave out. Unlike grants, an open-market purchase is paid for by the insider, at the market price. So far in 2026, the count stands at 3 purchases and no sales.

A typical purchase (the median) is worth €20k. On 10 out of 27 purchases, another insider of the same company was buying within the same 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. After 26 purchases with a full 90-day history, the hit rate stands at 23% and the median 90-day move at -35.6%. This is a record of the past, not a forecast.

On 31 August 2026 came the latest disclosure, an open-market purchase for €24k in Tonix Pharmaceuticals Holding Corp. Typically, a trade is published a median of 1 day after it takes place. Section 16 rules allow two business days to file each Form 4. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
