Shanghai Futures Exchange primary gold 1 kg. If you want to hedge, you need to buy 10000 lots in reverse. The current futures price is 335.25 yuan/gram, and the spot market price is (buy: 332.20 yuan/gram, sell: 332.42 yuan/gram).

If you have 10 tons of gold in your hand, do a sell hedge and short 10000 lots. If you are worried about the price drop, short it, and if you are worried about the price increase, do more. This is the principle of hedging.

We assume that when a perfect hedging is achieved on a certain day, the spot price is X and the futures price is Y.

Formula: (335.25-Y)+(X-332.42)=0.

X-Y=-2.83

As long as the difference between spot price and futures price is -2.83 yuan/gram, it is a perfect hedging.

If the spread is greater than -2.83, the hedging is successful and profitable.

If it is less than -2.83, the hedging is at a loss.

335.25 and 332.42 have changed every time, which needs to be handled according to the actual situation. These two figures are not dead figures, that is to say, the price of -2.83 is not a specific figure, but an example.

I hope you understand.
