Warren Buffett, The Oracle of Omaha, has given over US$68 billion to charity and has planned to further give US$140 billion by 2034. He is the largest billionaire donor in the world and pledge to give 99.5% of his wealth. However, he spoke on the overvaluation of today stock market and thinks it hard to find any good bargain in current market. He liken the stock market as a church with a casino connected to it and investors as gamblers. The heighten valuation is mainly fueled by AI stocks and the current value of AI stocks is more than US$600 billion. If it pops, it will be very ugly. Let's hope the most successful investor is wrong this time!
