Warren Buffett bets on Japanese conglomerates in his letter to shareholders. Buffett gives his investment lessons in two ways: with words and with actions.
Sometimes he sends messages, like when in the middle of the cryptocurrency bubble he disdained them as useless. Other times, it is his quarterly or annual reports or his statements of holdings that send the signals. Buffett prefers not to give excessive value in terms of the result of the exercise, although he considers it important to the extent that his portfolio evolves.
