The announcement of a dividend typically leads to a short-term decrease in the stock price by the amount of the dividend on the ex-dividend date, as the dividend payout is factored into the stock price. Since Western Union is paying out 23.5 cents per share, the stock is expected to open lower by that amount, which could be seen as a short-term negative impact. However, the overall impact on the stock price may be minimal as dividends are a regular part of Western Union's shareholder returns and are often anticipated by the market.
