We have very little insider data for 大洋 so far: the most recent filing dates from 13 January 2020. With so few records, no pattern can be drawn yet. Every figure here comes from the filings published by TWSE / TPEx (MOPS) and describes the past, not future prices; it is not investment advice.
Transparent value + quality ranking, distinct from the insider signal.
