Ng Hoi Ying, Michael

Ng Hoi Ying, Michael appears in our data through filings on Arts Optical International Holdings Ltd. shares, published by HKEX. Between 31 October 2018 and 27 December 2024, the trades on record add up to 9 filings.

Every open-market trade on record is a purchase: 9 purchases worth €7.0M, and no sale. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. In 2024 alone, the filings show 1 purchase and no sales.

The median purchase comes to €561k. Clusters matter here: 7 out of 9 purchases overlapped with buying by a colleague within 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. Ninety days after publication, 9 purchases show a median change of -1.2%, with the price up in 44% of them. This is a record of the past, not a forecast.

Most recently, on 30 December 2024, the filings show an open-market purchase worth €234k in Arts Optical International Holdings Ltd. Typically, a trade is published a median of 1 day after it takes place. This delay matters because a trade only becomes useful information once it is public. These figures are compiled from regulatory filings published by HKEX. They describe what insiders did and are not a recommendation.
