How the index is built
Each component is ranked against its own last 3 years, which is 756 sessions. A component needs at least 1 year of history, which is 252 sessions, to get a score.
The index is the average of the component scores available in a session. A session with fewer than 5 of the 7 components has no index.
History starts in 01/2020, so the first index value appears in early 2021.
The index describes the current state of the market and does not forecast prices.
Research on Vietnam finds that foreign flows mostly move together with prices rather than ahead of them.
We group each stock by its current exchange and use the current VN30 membership for past sessions too. A stock that has since moved off HOSE is therefore missing from HOSE history. This is a form of survivorship bias.
