John A. Olin

This profile gathers the share dealings of John A. Olin across 3 companies, led by Harley-Davidson, Inc., Westinghouse AIR Brake Technologies Corp and Herc Holdings Inc. Over a trading history stretching from 3 February 2016 to 5 March 2026, the count stands at 53 filings.

Both buying and selling appear: 3 purchases worth €1.5M, against 9 sales worth €9.2M. On balance, insiders were net sellers of €7.7M. 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 26 share grants and 15 option exercises. In 2026 alone, the filings show 1 purchase and 1 sale.

In size, the median ticket on the buying side is €362k. Of 3 purchases, 1 formed part of a group of insiders buying within 30 days of each other. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

Most recently, on 9 March 2026, the filings show a share grant in Westinghouse AIR Brake Technologies Corp. The most recent open-market purchase was published on 2 March 2026, 233 days ago. Typically, a trade is published a median of 3 days after it takes place. 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. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
