Charles Blum

Charles Blum has filed trades across 2 companies (mainly through SEC (Form 4)), most often in QS Energy, Inc. and Greenwave Technology Solutions, Inc. We count 4 filings; the first trade dates from 26 November 2012 and the latest from 1 February 2018.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

The record was last updated on 5 February 2018 with a transaction in Greenwave Technology Solutions, Inc. Typically, a trade is published a median of 4 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
