Ellen B. Richstone

Ellen B. Richstone, listed as board member, has filed trades across 5 companies (mainly through SEC (Form 4)), most often in Orion Energy Systems, Inc., Superior Industries International Inc and Cognition Therapeutics Inc. Over a trading history stretching from 13 June 2017 to 11 August 2026, the count stands at 42 filings.

On the market, this insider has only ever bought: 16 purchases, €320k 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. Outside the open market, there are 14 share grants and 12 option exercises.

The median purchase comes to €17k. On 10 out of 15 purchases, another insider of the same company was buying within the same 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

Most recently, on 12 August 2026, the filings show a share grant in Orion Energy Systems, Inc. The last insider purchase was made public on 24 February 2025, 604 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. US insiders must file a Form 4 within two business days of a trade. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
