哥倫布投資有限公司

All filings by 哥倫布投資有限公司 on record concern 保勝光學. Over a trading history stretching from 9 February 2015 to 5 November 2021, the count stands at 3 filings.

No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

The latest filing, published on 5 November 2021, reports a transaction in 保勝光學. The median gap between trade and publication is zero days: most filings appear on the same day. That lag is the time during which only the insider knows about the trade. Every figure here comes from the filings published by TWSE / TPEx (MOPS) and describes the past, not future prices; it is not investment advice.
