The amount of cash Buffett is holding is getting a little ridiculous. Berkshire's latest financial report shows cash reserves have reached $397.3 billion, roughly 2.7 trillion RMB. What does that mean? It's equivalent to one-fifth of South Korea's annual GDP and nearly half the total size of China's public equity funds. The thing is, Buffett has never been the type to just sit on cash. In 2016, he went heavy on Apple, in 2020 he bought into Japan's five major trading houses, and in 2022 he aggressively increased his stake in Occidental Petroleum. When the price is right, he moves faster than anyone. But over the past year and a half, he's been selling. His Apple holdings have been cut in half, Bank of America shares reduced from 1 billion to 500 million, and Amazon is almost completely sold off. After selling, he parked the money in short-term U.S. Treasury bonds, earning over $17 billion in annual interest—more than 120 billion RMB. A lot of people are asking: What exactly does Buffett see? The answer might be simple: He thinks the market is too expensive. Right now, the total market cap of U.S. stocks is nearly twice the GDP, sitting at historically high levels. The S&P 500 Shiller P/E ratio is over 35x, a level last seen during the 2000 dot-com bubble and just before the 1929 Great Depression. Buffett never predicts short-term market moves, but his actions speak louder than words. While the entire market is debating how much higher it can go, he's sitting on nearly $400 billion, waiting for the right opportunity. After decades of investing, he's learned that the most profitable times aren't when you rush in, but when others are panicking. Holding cash doesn't always mean you're bearish on the market—it often means you're waiting for better prices.
