James J. Lerner

This profile gathers the share dealings of James J. Lerner across 2 companies, led by Quantum Corp /DE/ and Seagate Technology Holdings plc. We count 38 filings; the first trade dates from 23 July 2014 and the latest from 21 April 2025.

The open-market side counts 4 purchases for €365k alongside 17 sales for €3.6M. Sales outweigh purchases by €3.2M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 12 share grants and 5 option exercises. In 2025 alone, the filings show no purchases and 3 sales.

A typical purchase (the median) is worth €23k. Of 4 purchases, 4 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. Ninety days after publication, 4 purchases show a median change of +8.0%, with the price up in 100% of them. This is a record of the past, not a forecast.

The latest filing, published on 23 April 2025, reports an open-market sale of €23k in Quantum Corp /DE/. The last insider purchase was made public on 13 August 2019, 2,645 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. US insiders must file a Form 4 within two business days of a trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
