Apple won back its crown as the most valuable publicly listed US company, ending yesterday's session on Wall Street with a market capitalisation above recent leaders Microsoft and Amazon.com.
Apple edged up 0.03%, putting its market value at $821.5 billion.
Microsoft's market capitalisation ended at $813.4 billion after its stock dipped 1.11%, while Amazon's stock market value finished the day at $805.7 billion, in third place, after its shares slid 1.12%.
Apple's stock has risen about 13% since its quarterly earnings report on January 29, with investors betting it was oversold following months of concern about a slowdown in iPhone demand and the company's rare revenue warning on January 2 related to soft demand in China.
But slowing iPhone sales have led to lower expectations for Apple's stock.
The average analyst price target for Apple has fallen from $240 three months ago to $175, less than a dollar more than its current stock price of $174.24.
After touching a record $1.1 trillion last October, Apple's market capitalisation fell gradually, and it was overtaken in December by Amazon and Microsoft, which have taken turns in the top position since then.
Apple's stock market value hit a low of $675 billion on January 3 after its revenue warning, but then steadily recovered, helped in part by a quarterly report that was better than feared by investors.
While Apple has gained in recent sessions, Microsoft and Amazon's shares fell after their quarterly reports.
Amazon has declined almost 5% since last Thursday, when it forecast first-quarter sales below Wall Street estimates and said it would step up investments in 2019.
Microsoft's stock is fairly flat from last Wednesday, when the software maker met targets for its quarterly results and forecast.
