J. Alberto Arias is a declared insider of Sierra Metals Inc. (formerly Dia Bras Exploration Inc.), with filings sourced from SEDI. The record holds 108 filings, for trades running from 21 November 2008 to 18 March 2025.

The open-market side counts 24 purchases for €397k alongside 66 sales for €1.3M. Sales outweigh purchases by €893k. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The rest of the record consists of 9 option exercises. 2025 to date brings no purchases and 40 sales.

Half of the purchases are above €3,601 and half below. The 24 purchases reviewed show no overlap with other insiders buying the same stock within a month.

The record was last updated on 18 March 2025 with an open-market sale (€501) in Sierra Metals Inc. (formerly Dia Bras Exploration Inc.). The last insider purchase was made public on 16 January 2019, 2,835 days ago. Between a trade and the moment it shows up on SEDI, the median delay is 4 days. Until a filing is published, the market cannot know about the trade. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Every figure here comes from the filings published by SEDI and describes the past, not future prices; it is not investment advice.
