The announcement of new products like the Calculator app for iPad and new iPads could positively impact Apple's stock in the short term due to increased user engagement and potential sales. However, the significant drop in iPhone sales in China and the reduction in Vision Pro shipment forecasts are likely to have a negative impact on investor sentiment and Apple's stock price in the short term. The negative aspects, especially the sales slump in a major market like China, could outweigh the positive news.

Zuckerberg's comments on Apple's Vision Pro reflect ongoing competition and rivalry in the tech industry, particularly in the AR space. While his criticism may not directly impact Meta's stock price in the short term, it highlights Meta's stance on AR technology and could influence investor perception regarding the company's direction and potential in the AR market. However, the impact is likely to be neutral as it does not directly pertain to Meta's financial performance or market position.
