Charles Biederman

Charles Biederman, listed as board member, appears in our data through filings on ONE Liberty Properties Inc shares, published by SEC (Form 4). Between 24 February 2006 and 14 January 2026, the trades on record add up to 82 filings.

On the open market, the record shows 12 purchases worth €179k and 30 sales worth €266k. Sales outweigh purchases by €86k. 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 22 share grants.

Half of the purchases are above €13k and half below. Ninety days after publication, 11 purchases show a median change of +0.6%, with the price up in 91% of them. This is a record of the past, not a forecast.

The record was last updated on 16 January 2026 with a share grant in ONE Liberty Properties Inc. The last purchase on record was published on 8 September 2015, which is 4,064 days ago. The median gap between a trade and its publication by SEC (Form 4) is 5 days. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
