Charles E. Davidson: trading record in brief
Charles E. Davidson is a declared insider at 4 companies; the most frequent names are Gulfport Energy Corp, Republic Airways Holdings Inc. and Bronco Drilling Company, Inc. We count 26 filings; the first trade dates from 3 January 2006 and the latest from 17 June 2026.
The open-market side counts 2 purchases for €13.2M alongside 22 sales for €329.3M. Sales outweigh purchases by €316.1M. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket.
The record was last updated on 22 June 2026 with a transaction in Mammoth Energy Services, Inc. The last purchase on record was published on 30 May 2007, which is 7,102 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. For comparison, the SEC allows two business days to file a Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
