Just two years after Apple became the first publicly listed U.S. company with a $1 trillion stock market value, the iPhone maker has now topped $2 trillion.

The Cupertino, California-based company’s shares briefly rose to as high as $468.65 on Wednesday, equivalent to a market capitalization of $2.004 trillion. The stock was last up 1.2% at $467.62, giving Apple a market capitalization of $1.999 trillion.

Buoyed by bets on the long-term success of the country’s biggest tech names in a post-coronavirus world, Apple’s shares have surged since blowout quarterly results in July that saw the iPhone maker eclipse Saudi Aramco as the world’s most valuable listed company. Apple’s stock is up about 57% so far in 2020.

Apple now accounts for close to 7% of the S&P 500’s total market value. Its market capitalization is about equal to the combined values of the S&P 500’s 200 smallest companies.

However, Apple’s recent stock rally has left it potentially overvalued, according to a widely used metric. The stock is trading at over 30 times analysts’ expected earnings, its highest level in more than a decade, according to Refinitiv.

Those and other heavyweight technology companies have surged to record highs during the coronavirus pandemic as consumers rely more on ecommerce, video streaming and other services they provide. Investors are betting these companies will emerge from the pandemic stronger than smaller competitors, with some even viewing their volatile shares as safe havens.

Apple’s revenue grew across every category and all of its geographical regions in the June quarter, even as the coronavirus crisis caused the U.S. economy to contract at its worst rate since the Great Depression.

The iPhone maker is slated to split its stock four-for-one when trading opens on Aug. 31, with the company saying it aims to make its shares more accessible to individual investors.
