The substantial discount on a high-end product like the 16-inch MacBook Pro with M1 Max chip is likely to attract consumers and lead to an increase in sales. This promotion is significant as it applies to a premium configuration, which could result in a higher average selling price and potentially boost Apple's revenue in the short term. However, the impact on the stock price may be moderate as such sales events are common during the holiday season and might already be factored into the stock price.
