aTyr Pharma Insider Transactions Over The Last Year

The Independent Director Paul Schimmel made the biggest insider purchase in the last 12 months. That single transaction was for US$912k worth of shares at a price of US$0.94 each. So it’s clear an insider wanted to buy, at around the current price, which is US$0.98. Of course they may have changed their mind. But this suggests they are optimistic. While we always like to see insider buying, it’s less meaningful if the purchases were made at much lower prices, as the opportunity they saw may have passed. In this case we’re pleased to report that the insider purchases were made at close to current prices.
