I don't think your statement is correct. Hedging is to avoid risks. The basis risk you mentioned only considers the profit and loss of futures unilaterally. Hedging is actually a joint hedging combination of spot and futures, which cannot be discussed separately, otherwise it is meaningless.

The biggest problem of hedging, which can also be said to be risk, is the determination of hedging rate. Because the fluctuation direction and amplitude of futures and spot prices are difficult to be completely consistent, there is a problem of hedging rate in naughty hedging. It is very important and complicated to choose the proportion of spot and futures. This is one of the risks.

In addition, because there is still a certain difference between futures and spot, although it is rare, it does not rule out that futures and spot are inversely related, so hedging will be completely ineffective. This market risk is also a risk.

To say other risks, there are operational risks, that is, when hedging, the choice of contract month is unreasonable, which leads to the need to move the warehouse to the month or delivery.

In short, hedging also needs good risk management, which is not as simple as the book says.

For futures, if you still need or have questions, you can contact me directly.
