Forex, futures, and stocks are all financial products, but their risks and trading methods are different. Foreign exchange refers to the exchange of one currency for another, usually used for international trade and investment. The risk of foreign exchange mainly comes from market fluctuations and changes in exchange rates because changes in exchange rates may lead to changes in the value of assets. Foreign exchange trading methods include buying and selling. Buying has lower risk but lower returns, while selling has higher risk but higher returns. A futures contract is a contract to buy or sell a commodity or service at a specific price at a certain time in the future. The risk of futures mainly comes from market fluctuations and fluctuations in the maturity price because the price of futures is usually affected by the relationship between supply and demand in the market. The trading methods of futures include buying and selling. Selling has lower risk but lower returns, while buying has higher risk but higher returns. A stock was a proof of ownership that represented a person's ownership of a certain amount of a company. The risk of stocks mainly comes from market fluctuations and company earnings because stock prices are usually affected by the supply and demand of the market. The trading methods of stocks include buying and selling. Buying has lower risk but lower returns, while selling has higher risk but higher returns. Among the three, stocks with lower risk may be relative to foreign exchange and futures. Although the returns of stocks are relatively low, the risks are also low because the stock market is relatively stable and the company's earnings are relatively stable. The futures and foreign exchange markets were riskier and more volatile, so their returns were relatively higher.
