Michael Whang: trading record in brief
All filings by Michael Whang on record concern Amtech Systems Inc. Over a trading history stretching from 1 June 2018 to 28 November 2022, the count stands at 12 filings.
The open-market side counts 1 purchase for €9,049 alongside 3 sales for €342k. Taken together, the sales exceed the purchases by €333k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 1 share grant and 7 option exercises. 2022 to date brings no purchases and 2 sales.
On 30 November 2022 came the latest disclosure, a share grant in Amtech Systems Inc. The latest purchase dates back some time: it was published 2,442 days ago, on 3 March 2020. Filings reach the SEC (Form 4) feed a median of 1 day after the trade. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
