Understanding Ex-Dividend Dates and Their Impact on Stock Prices<\/h2><\/div>

In the Vietnamese stock market, the question \"\"should I sell stocks before or after the ex-dividend date\"\" is always a topic of interest among investors. To answer this question thoroughly, we first need to understand what an ex-dividend date is and how it affects stock prices.<\/p><\/div>

The ex-dividend date is the day when buyers of a stock will no longer receive the benefits from the upcoming dividend payment. In Vietnam, this date usually occurs one trading day before the record date and has significant implications for investors' trading strategies.<\/p><\/div>

On ex-dividend date<\/td>Stock price will be technically adjusted<\/td>Price decreases corresponding to dividend value<\/td><\/tr>
After ex-dividend date<\/td>Buyers no longer receive benefits from this dividend<\/td>Price already reflects the dividend deduction<\/td><\/tr><\/tbody><\/table><\/div><\/div>

In the Vietnamese stock market, according to regulations from the Ho Chi Minh City Stock Exchange (HOSE) and Hanoi Stock Exchange (HNX), stock prices will be technically adjusted on the ex-dividend date using the formula:<\/p><\/div>

Adjusted price = (Closing price on cum-dividend date \u00d7 Number of shares before rights execution - Cash dividend value) \/ Number of shares after rights execution<\/p><\/div>

Analysis of Stock Price Behavior Around Ex-Dividend Dates in Vietnam<\/h2><\/div>

Actual research on the Vietnamese stock market reveals some interesting patterns in stock price movements before and after the ex-dividend date. Understanding these patterns will help you answer the question of \"\"should I sell stocks before or after the ex-dividend date\"\" appropriate to each situation.<\/p><\/div>

Psychological Effect Before Ex-Dividend Date<\/h3><\/div>

According to data collected from companies listed on HOSE and HNX, most stocks tend to increase in price within 5-10 days before the ex-dividend date. This phenomenon is explained by investors' psychology of wanting to own stocks to receive dividend benefits.<\/p><\/div>

Stock Group<\/th>Average Increase Before Ex-Dividend Date<\/th>Occurrence Rate<\/th><\/tr><\/thead>
VN30<\/td>2.5% - 3.5%<\/td>75%<\/td><\/tr>
Midcap<\/td>3.0% - 4.5%<\/td>68%<\/td><\/tr>
Smallcap<\/td>4.0% - 6.0%<\/td>60%<\/td><\/tr><\/tbody><\/table><\/div><\/div>

Experts at Pocket Option note that this effect is typically stronger for stocks with high and stable dividend payout ratios. Notable examples include stocks like REE, FPT, or PHR, which have shown significant increases before the ex-dividend date in recent years.<\/p><\/div>

Price Reaction After Ex-Dividend Date<\/h3><\/div>

After the ex-dividend date, stock prices will decrease corresponding to the distributed dividend value. Interestingly, this decrease is not always exactly equal to the dividend value. Analysis of data from the Vietnamese market during 2018-2024 shows:<\/p><\/div>
