The news of Mastercard Foundation selling its Mastercard stock over a 7-year period may cause some investors to be concerned about the stock's future performance. However, the long-term nature of the plan and the fact that the foundation will still retain a significant overweight holding of Mastercard in its portfolio should mitigate the impact on the stock price. The score of -1 reflects the slight downward pressure on the stock price, but the importance and confidence scores indicate that the impact is expected to be minimal.
