Stock market reaction to cash dividends: evidence from the Nigerian stock market

Abstract

Purpose

Very little is known about the effect of dividend announcements on stock prices in Nigeria, despite the country’s unique institutional environment. The purpose of this paper is, therefore, to provide empirical evidence on this issue by investigating the stock price reaction to cash dividends by companies listed on the Nigerian Stock Exchange.

Design/methodology/approach

Standard event study methodology, using the market model, is employed to determine the abnormal returns surrounding the cash dividend announcement date. Abnormal returns are also calculated employing the market-adjusted return model as a robustness check and to test the sensitivity of the results to β estimation. The authors also examine the interaction between cash dividends and earnings by estimating a regression model where announcement abnormal returns are a function of both dividend changes and earnings changes relative to stock price.

Findings

The study find support for the signaling hypothesis: dividend increases are associated with positive stock price reaction, while dividend decreases are associated with negative stock price reaction. Companies that do not change their dividends experience insignificant positive abnormal returns. The results also suggest that both dividends and earnings are informative, but dividends contain information beyond that contained in earnings.

Research limitations/implications

The sample for the study includes only cash dividend announcements occurring without other corporate events (such as interim dividends, stock splits, stock dividends, and mergers and acquisitions) during the event study period. The small firm-year observations may limit the validity of generalizations from these conclusions.

Practical implications

The findings are useful to researchers, practitioners and investors interested in companies listed on the Nigerian stock market for their proper strategic decision making. In particular, the results can be used to encourage transparency and good governance practices in the Nigerian stock market.

Originality/value

This paper adds to the very limited research on the stock market reaction to cash dividend announcements in Nigeria; it is the first of its kind employing a unique cash dividends data.
