Yes, as is Apple and many other companies, but I would bet that it isn't sitting rotting away as cash. In 2021 alone, Apple purchased about $110 billion in marketable securities, this is public knowledge. Hence, the vast majority of Apple's cash and many other companies with lots of cash does get invested.You do realize that Berkshire Hathaway is sitting on top of 149 billion in cash right? And instead of reinvesting the money, lots of company just buy back their stock with profits to boost up the price instead of investing it.
