The ex-dividend date typically results in a stock opening lower to reflect the dividend payout. In this case, NVIDIA's stock is expected to open 4 cents lower on Wednesday. However, this is a normal occurrence for stocks on their ex-dividend date and does not indicate a negative impact on the company's overall performance. The dividend payout is a positive for shareholders who own the stock by the end of Tuesday's session, as they will receive the 4 cents per share dividend on June 30, 2023.
