Si-Hui Tan: trading record in brief
All filings by Si-Hui Tan on record concern Horizon Quantum Holdings Ltd. Over a trading history stretching from 20 August 2026 to 12 September 2026, the count stands at 3 filings.
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.
The record was last updated on 15 September 2026 with a share grant in Horizon Quantum Holdings Ltd. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. For comparison, the SEC allows two business days to file a Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
