Berkshire Hathaway Inc.'s (NYSE:BRK) (NYSE:BRK) quarterly cash reserves have officially swollen to an unprecedented $397 billion.

This staggering financial war chest effectively gives the multi-national conglomerate enough liquidity to outrightly purchase almost any individual corporate entity among 474 different companies currently listed within the S&P 500 index.

To put this historic capital accumulation into perspective, market commentators like Barchart noted that Berkshire "could buy any 1 of the 474 S&P 500 or up to maybe 15–20 of the lowest market cap S&P 500 companies." It last stood at $373 billion before its first-quarter earnings in May.

This liquidity builds on the first quarter, where the company completely exited more than 15 stock positions while adding new stakes in Alphabet Inc.
