The comment pointed out that the COMBINED market caps of Microsoft, Google, Facebook and Amazon, four of Apple’s major peers in the tech world, still didn’t equal Apple’s. Total market cap value of the four companies equals $630.95B. Meanwhile, Apple currently clocks in at $632.56B. Just staggering when you think about it. Especially when you consider that Apple’s market cap in 1999 was only $9.29B.
