Using leverage to make high-risk investments usually involves borrowing money to increase the size of an investment, which can increase potential returns and risks. Here are some common ways to leverage investments: 1. **Margin trading**: In the stock, futures or foreign exchange markets, borrowing money from a broker to buy more securities. Investors are required to deposit a certain percentage of margin, and if the market moves unfavorably, they may need to add margin or close their positions. 2. **Futures contracts**: The futures market allows you to lock in future prices through contracts, which can control large amounts of assets with a small initial margin. In the case of large price fluctuations, it may result in higher losses or gains. 3. **Leveraged ETFs**: Leveraged exchange-traded funds (ETFs) are designed to amplify the intraday returns of their underlying index. They usually use derivatives and debt financing to achieve this goal and are suitable for short-term speculation. 4. **Option trading**: Buying call or put option contracts allows investors to gain control over the price fluctuations of large assets at a small cost. Options have high leverage, but if they do not make a profit at expiration, investors may lose their entire investment. 5. **Contract for Difference (CFD)**: A derivative financial instrument that allows investors to speculate on prices without holding actual assets. CFDs typically offer high leverage, low capital requirements, but high market risk. 6. **Margin Loans**: Using stocks or other assets as collateral to obtain loans to invest more. However, please note that if the value of your investment decreases, you may trigger a margin call or forced liquidation. Highly leveraged investments are very risky and may result in loss of principal or even debt. Therefore, investors are advised to fully understand the risks involved, carefully assess their risk tolerance, and consider consulting a professional financial advisor.
