BlockBeats News, February 23rd, Berkshire Hathaway's Chairman and CEO Warren Buffett stated in this year's annual shareholder letter: "While some commentators currently view Berkshire's large cash holdings as an unusual condition, the majority of your funds are still invested in equities. This preference will not change. Although our holdings in publicly traded stocks decreased from $354 billion last year to $272 billion, the value of our privately held businesses has increased and still far exceeds the value of our stock portfolio."
Berkshire shareholders can rest assured that we will always allocate the majority of your funds to stocks—primarily U.S. stocks, many of which have significant international operations. Berkshire will never favor holding cash equivalents over owning great businesses, whether in full or in part."
Furthermore, the shareholder letter stated that Berkshire has been consistently increasing its borrowings denominated in yen, but not following any fixed pattern. All borrowings are at fixed rates, with no "floating rate" borrowings. "I have no idea what the future exchange rate movements will be, so we seek to maintain a position that is approximately neutral with respect to currencies."
It is worth noting that this year's shareholder letter did not mention cryptocurrencies.
