Isolating the market reaction to a governance resolution: A market-model event study of eximbank’s 2026 AGM

Abstract
This study extends a prior descriptive
analysis of stock-market reactions to governance and ownership events at
Vietnam Export Import Commercial Joint Stock Bank (Eximbank). Descriptive
comparisons of raw share-price and trading-volume changes can show whether a
market reacts, but cannot separate a firm-specific reaction from market-wide
movement. Using a market-model event study with the VN-Index as the market
proxy, this study isolates the abnormal return around Eximbank’s 2026 Annual
General Meeting (AGM). The announcement-day abnormal return is negative
(-3.47%) and marginally significant, while the cumulative abnormal return over
the surrounding windows is not statistically significant. The reaction was
therefore sharp but transient, refining the view that the AGM produced the
weakest market response and demonstrating the value of abnormal-return analysis
over raw price comparison.
