The efficient market hypothesis states that the stock market reflects all known information by quickly processing and assimilating new data via the mechanism of buying and selling. Moreover, the stock market is forward-looking, explaining why a company's stock price may fall even if earnings improve from the previous quarter. In order to increase their market capitalization, large companies outperform market expectations for earnings. In order to artificially boost their stock prices, they manipulate their earnings reports frequently to meet or exceed estimates. In other words, the Securities and Exchange Commission (SEC) pays a lot of attention to how companies manage their earnings.

Apple’s journey in the stock market has been marked by long-term expansion as well as periods of significant volatility. The company entered the public market in 1980 with shares priced at $22. Because Apple has completed five stock splits, the original IPO price equals approximately $0.10 on a split-adjusted basis. Over the following decades, Apple expanded its product range and became a major force in consumer technology. The Macintosh established its presence in personal computing, while the iPod, iPhone, and iPad opened new sources of growth. Apple’s services business subsequently added further revenue opportunities. These developments were reflected in the company’s rising market value and stock price over the long term. Apple shares experienced especially strong gains in years such as 2019 and 2020 and also posted substantial increases in 2023 and 2024. The company has also returned capital through dividends and buybacks. Still, Apple’s stock has experienced declines and corrections, making risk and market conditions important considerations for investors.
