Many people do not understand one thing: Why does the global market often become nervous when the US stock market falls? It's not because there's magic in the American market. But now the global financial system is already interconnected. The US stock market is not an isolated island. The US dollar, US bonds, technology companies, and global funds are almost all tied to the US market. If the Federal Reserve moves, the global cost of funds will change. If the yield of US bonds moves, the valuation of stocks will change. As the US dollar strengthens, emerging market exchange rates and external debt pressures will change. A drop in US technology stocks will also affect the sentiment of global growth stocks. So the decline in the US stock market is not only affecting American investors. It will spread to other markets through funds, exchange rates, interest rates, industry chains, and emotions. China, Japan, and South Korea appear to be three different markets. But they are also in the global funding network. China looks at policies, manufacturing industry, consumer demand, and RMB assets. Japan looks at the Japanese yen, low interest funds, automotive electronics, and overseas income. South Korea looks at semiconductors, storage chips, exports, and the global technology cycle. They each have their own logic, but they can also be influenced by the same external variable: Global capital risk appetite. When global funds are willing to take risks, growth stocks, technology stocks, and emerging market assets are usually more comfortable. When funds start to seek safety, many assets will come under pressure together. But there is a misconception here: Linkage does not mean complete synchronization. A decline in the US stock market does not necessarily mean a decline in A-shares. The rise of the US stock market does not necessarily mean that the Asian market will rise. The impact direction and intensity of the same external event on different markets may be completely different. For example, the strengthening of the US dollar may be a capital outflow for US assets, but it may be exchange rate pressure for some emerging markets. The rise in US bond yields may be another logic for bank stocks, but it is valuation pressure for overvalued technology stocks. So when looking at the global market, we cannot just look at the ups and downs. We need to look at the transmission path behind it. A complete financial system is not limited to the stock market. It includes: Central bank, currency, interest rates, banks, funds, insurance, pension funds, bonds, foreign exchange, commodities, derivatives, enterprises, residents, government. The stock market is just a part of it. Many times, the stock market reflects emotions first, but what truly determines the long-term direction are corporate revenue, profits, employment, and economic growth. Global stock markets will influence each other, but they will not mechanically replicate. What really matters is not that the US stock market has fallen, but what it has changed: Capital cost, risk preference, exchange rate direction, industry chain expectations, or corporate profitability.
