Robert W. Eifler: trading record in brief

This profile gathers the share dealings of Robert W. Eifler across 2 companies, led by Noble Corp plc and Noble Corp. Over a trading history stretching from 5 February 2022 to 4 September 2026, the count stands at 14 filings.

The open-market side counts 1 purchase for €336k alongside 2 sales for €4.8M. Taken together, the sales exceed the purchases by €4.5M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Besides market trades, the filings include 1 share grant and 8 option exercises. Since January 2026: no purchases and 1 sale on the market.

The newest entry dates from 8 September 2026: a transaction, in Noble Corp plc. The clock since the last published purchase (20 February 2025) now reads 605 days. The median gap between a trade and its publication by SEC (Form 4) is 3 days. The legal deadline for a Form 4 is two business days after the transaction. 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.
