Mark e. Strome

Mark e. Strome is a declared insider at 2 companies; the most frequent names are Zivo Bioscience, Inc. and HeartBeam, Inc. The record holds 10 filings, for trades running from 2 June 2021 to 17 April 2026.

Market trades split into 5 purchases (€2.5M) and 1 sale (€762k). Netting one side against the other leaves €1.8M of net buying. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 2 share grants. In 2026 alone, the filings show 3 purchases and no sales.

In size, the median ticket on the buying side is €216k. 3 out of 5 purchases came within 30 days of a purchase by at least one other insider of the same company. Purchases made close together by different insiders form what is called a cluster. For 4 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 25% of cases, with a median move of -36.9%. They describe history only and say nothing certain about the share price ahead.

The record was last updated on 24 April 2026 with an open-market purchase (€170k) in Zivo Bioscience, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 5 days. Section 16 rules allow two business days to file each 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.
