Secondly, enterprises should hedge their risks through financial instruments and industrial chains. The function of futures lies in discovering prices and hedging. Hedging is essentially hedging big risks with small costs, not nominal hedging. There is no such thing as a free lunch, so managing the hedging risk requires the cost of purchasing futures options. In the era of negative growth, negative interest rate and negative oil price, the market price is not unusual. Oil production, supply, demand, trade, investment and other parties need to hedge risks through derivatives such as futures and options, otherwise once the price fluctuates sharply, the risks will be uncontrollable. Therefore, enterprises should improve their ability to master risk hedging tools such as futures options. For example, try to buy put options or call options and try not to sell options. Because buying options means you have the option to exercise, while selling options means unlimited risks. Not to mention the Cao incident, the negative growth of oil prices is just around the corner.
