“…There are three reasons why the fact-finding approach is ideal for studying the influence of former bank executives' legal involvement on the market share. First, a company's future earnings are reflected in current stock earnings [26] Second, stock prices adjust to event announcements [24,25]. Third, stock prices reflect an unbiased estimate of future earnings suggesting that the stock market is inefficient [11].…”

The main objective of this article is to study the impact of a scandal with the Vice Chairman of the Founding Board - VCFB (former member of the Board of Directors - BoD) and the former General Manager of Asia Commercial Bank (ACB) on the daily returns of shares of 9 sectors of the Vietnam’s stock market. The event study method is used for each industry with many different event windows. Research results show that the announcement of an arrest warrant is an entirely unexpected event for the stock market because no industry reacts significantly in the days before the event. The reaction of industries was strongest 5 days after the event for the Banking and Finance industries and 2 days after the event for non-financial industries. The conclusion of the study shows that although the information is directly related to one bank - ACB, its spillover effects have covered all nine industries including the financial and non-financial industries on the Vietnam stock market (VST). The nature of cross-ownership among commercial banks in Vietnam (CB Vietnam) explains that negative information only creates a spillover effect within the industry but does not have a competitive effect in this industry. Social networks amplify herd mentality and spillover effects, negatively impacting the financial and non-financial industries in the stock market.

Traditional wet markets are the main source of fresh food and the largest source of daily nutrient intake for citizens of Hanoi. Nevertheless, due to the lack of traceability and sales registration systems, food flows within these markets remain largely invisible. This makes it challenging to assess the impact of shocks, such as pandemics, on these markets. In this paper, we characterize the impact of COVID-19 by analyzing data from 25 Wi-Fi access points installed in five formally established wet markets. The study timeframe covers a pre-pandemic period from July 2019 to the end of the initial stage of the pandemic in November 2020. While providing free Internet access, data were continuously collected about devices in close vicinity to the access points. Based on this information, we tested five hypotheses about the number, frequency, time, and duration of visits to the markets as well as changes in inter-market activities. The results show that during the shock (February to mid-April 2020) and aftershock (mid-April to July 2020) periods, market actors significantly decreased the total number of market visits (-26% P < 0.001) and the frequency of market visits (up to -47% for very frequent market users, P < 0.001). The number of inter-market visits dropped sharply during the shock period (66% $$\pm$$ ± 17% of the baseline level, P < 0.001), and the peak time for market shopping shifted significantly by 90 min later in the day, P < 0.001. No change was observed in visit duration. Several factors identified in existing literature as affecting consumer behaviors provide possible explanations for the changes observed. We present a set of recommendations to limit the negative impact of the pandemic in terms of food security and livelihoods in Hanoi and to mitigate consumers’ negative perception of wet markets in terms of food safety.
