套期保值是金融市场中的一种投资策略，它通过购买和出售金融衍生品来实现对现货资产价格波动的预测和规避风险。这种策略对于企业尤其重要，因为它可以帮助企业有效管理财务风险，保护利润并保持盈利稳定性。
套期保值的基本原理是在市场上同时进行买入和卖出相同数量的同类合约，这样即使一方合约价格变动，也能通过另一方合约抵消损失。例如，如果某公司生产的是原油，为了保护自己不受原油价格下跌带来的影响，可以在原油价格高时卖出 futures 合约，并将这些销售收入用于生产或储存。在此期间，如果原油价格确实下跌了，该公司就可以按照合同规定的低价购买所需的原油，从而减少了因成本增加而可能出现的亏损。
套期保值案例：多伦多铜业
多伦多铜业（TTC）是一家全球性的矿产开采公司，以其对金属资源如铜、金、银等的大规模开采闻名。作为一个依赖于自然资源价值变化的大型矿业公司，TTC faced significant price volatility in the commodities market. To mitigate this risk, they employed a strategy of hedging using futures contracts.
In 2018, copper prices were plummeting due to global economic uncertainty and trade tensions. TTC had already produced a large amount of copper for the year but hadn't yet sold it all. They realized that if they waited too long to sell their inventory, they might end up selling at lower prices than what was currently available on the futures market.
To counteract this potential loss, TTC bought put options on copper futures contracts with an expiration date matching when their inventory would be ready for sale. By doing so, they could lock in a minimum selling price for their future production while still having the opportunity to benefit from higher prices if conditions improved before delivery.
When copper prices continued to drop even further after purchasing these put options, TTC exercised them and sold their inventory at the locked-in price. This effectively protected them from losses caused by falling commodity prices and ensured a stable profit margin despite market fluctuations.
Through implementing this strategic use of derivatives as part of its overall risk management plan, Toronto Mining Company managed not only to protect itself against adverse price movements but also demonstrated how businesses can leverage financial tools like derivatives to enhance profitability and resilience in volatile markets.
