Filings by John P. Miller span 3 companies, the busiest being Spruce Power Holding Corp, Capstone Energy Plus, Inc. and Power Solutions International, Inc. Between 15 June 2017 and 1 September 2026, the trades on record add up to 16 filings.

Every open-market trade on record is a purchase: 4 purchases worth €131k, and no sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Besides market trades, the filings include 12 share grants.

The median purchase comes to €33k. On 3 out of 4 purchases, another insider of the same company was buying within the same 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The record was last updated on 3 September 2026 with a share grant in Capstone Energy Plus, Inc. The latest purchase dates back some time: it was published 333 days ago, on 25 November 2025. Filings reach the SEC (Form 4) feed a median of 3 days after the trade. Section 16 rules allow two business days to file each Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
