David Wallace Cornhill

David Wallace Cornhill is a declared insider of Alterra Power Corp., with filings sourced from SEDI. The record holds 4 filings, for trades running from 6 September 2016 to 6 February 2018.

Not one of the filings records a straightforward purchase or sale on the market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

Most recently, on 9 February 2018, the filings show a transaction in Alterra Power Corp. Filings reach the SEDI feed a median of 3 days after the trade. That lag is the time during which only the insider knows about the trade. Source: insider filings from SEDI. Past trades are no guide to future returns.
