Robert J. Bitterman

Robert J. Bitterman, listed as board member, appears in our data through filings on Phio Pharmaceuticals Corp. shares, published by SEC (Form 4). The record holds 30 filings, for trades running from 15 February 2022 to 28 September 2026.

On the market, this insider has only ever bought: 20 purchases, €54k in total. No amount is published for 1 filing, which the totals therefore leave out. 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 10 share grants. In 2026 alone, the filings show 4 purchases and no sales.

Half of the purchases are above €2,103 and half below. Of 20 purchases, 10 formed part of a group of insiders buying within 30 days of each other. Purchases made close together by different insiders form what is called a cluster. Looking at 15 purchases old enough to measure, the stock rose over the following 90 days in 53% of cases; the median change was +1.8%. They describe history only and say nothing certain about the share price ahead.

Most recently, on 29 September 2026, the filings show a share grant in Phio Pharmaceuticals Corp. The latest purchase is recent: it was published 24 days ago, on 23 September 2026. The median gap between a trade and its publication by SEC (Form 4) is 2 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.
