Long refers to optimistic about the future rising prospects of the stock or foreign exchange and futures, and there will be room for profit after buying. Long is long. In short, long is to buy stocks or foreign exchange and other products. Shorting is the opposite, that is, not optimistic about recent stocks or foreign exchange, futures and other products, thinking that continuing to hold them later will lead to losses and selling stocks, foreign exchange and other products.

Which is more profitable, long or short?

There is no specific standard for making more money by going long or shorting. The market conditions of stocks, foreign exchange and futures are unpredictable, and no one knows whether the market is empty or long in the later period. Generally speaking, if it is for China stock market, it will be more profitable to go long, because China stock market is only allowed to go long, and there is no option to short. Although investors can short through margin financing and securities lending, the demand for investors' securities lending is very high, and the securities they short are limited, so few people in China stock market make money by shorting.

If it is a foreign stock market, it depends on the investment level of investors, whether to make money by shorting or making more money, because foreign stock markets allow investors to short, so there will be great changes every day. Foreign stock markets and domestic stock markets are different in many places. The risk of foreign stock trading is greater than that of domestic stock market. Foreign stock markets adopt T+0 trading system, while domestic stock markets adopt T+/KLOC-0 trading system.

For China's futures market, there are many structural market models in China, and it will be more difficult to make money by shorting. But in theory, shorting can only earn 100% at most, and the loss is infinite. The maximum loss is 100%, and its profit space is infinite.

However, in any case, investing in stocks, foreign exchange and futures is very risky. It is recommended to buy according to your risk tolerance. The investment risk of futures may even be higher than that of stocks, with a higher threshold.
