The announcement of a 42 cents per share dividend by CRA International (CRAI) is significant for investors. The stock is expected to open lower on the ex-dividend date, reflecting the dividend payout. This short-term price adjustment is typical as the market accounts for the cash outflow from the company to its shareholders. Investors looking for dividend income might see this as an attractive opportunity, while short-term traders might be cautious about the expected dip in price.
