The downgrade from Buy to Hold by a major bank like DZ Bank could lead to a neutral short-term impact on Apple's stock price. The announcement of a $180 price target suggests a belief in the stock's stability or slight growth potential, but the downgrade indicates a more cautious outlook. Investors may interpret this as a signal to hold off on buying more shares or to reassess their investment in Apple, potentially leading to a stabilization or minor fluctuation in stock price.
