William J. Miller

William J. Miller discloses dealings in 5 companies, chiefly Nvidia Corp, Waters Corp /DE/ and Digimarc Corp. The record holds 123 filings, for trades running from 3 January 2006 to 5 December 2017.

On the open market, the record shows 4 purchases worth €140k and 52 sales worth €30.3M. Taken together, the sales exceed the purchases by €30.2M. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Outside the open market, there are 30 share grants and 35 option exercises. So far in 2017, the count stands at no purchases and 1 sale.

A typical purchase (the median) is worth €31k.

On 6 December 2017 came the latest disclosure, an option exercise for €226k in Waters Corp /DE/. The most recent open-market purchase was published on 19 November 2012, 5,102 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. US insiders must file a Form 4 within two business days of a trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
