The London Metal Exchange is the largest metal trading futures market in the world. Generally speaking, China's non-ferrous metals such as aluminum, zinc and nickel are exported, while copper is imported. In fact, the prices of these metals are greatly influenced by lme. Although there are occasional deviations, most of them rise and fall together. In fact, the rise and fall of commodity prices directly affects the trend of the world economy, or the trend of the world economy directly affects the trend of industrial products such as metals. Once lme plummets, it often means economic collapse or industrial collapse, which also has a serious impact on the stock market. In fact, the plunge of China stock market last year can be said to have started from the futures market.

Cmx is not like this, mainly engaged in agricultural futures, which is completely different from lme. The price of agricultural products is mainly influenced by climate, war and output factors, not by industry and economy. In fact, even during the economic crisis, the prices of agricultural products are unlikely to fall too seriously. After all, you can't say that you don't eat rice or wheat because of the financial crisis. This is absolutely impossible, so his relationship with the stock market is not very close. Of course it's impossible.

Generally speaking, lme, like Dow Jones, is actually one of the barometers of the world economy, even more important.
