Phillip P. Chan: trading record in brief
Phillip P. Chan is a declared insider of Cytosorbents Corp (chief executive), with filings sourced from SEC (Form 4). The record holds 62 filings, for trades running from 4 September 2012 to 15 September 2026.
In open-market terms, that means 21 purchases worth €626k on one side and 5 sales worth €344k on the other. Purchases outweigh sales by €282k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Besides market trades, the filings include 22 share grants and 9 option exercises. In 2026 alone, the filings show 4 purchases and no sales.
In size, the median ticket on the buying side is €22k. As a share of market capitalisation, the median purchase stands at 0.14%, based on 3 purchases. Of 20 purchases, 10 formed part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. For 18 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 44% of cases, with a median move of -16.0%. They describe history only and say nothing certain about the share price ahead.
The newest entry dates from 16 September 2026: an open-market purchase of €20k, in Cytosorbents Corp. The median gap between a trade and its publication by SEC (Form 4) is 2 days. 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.
