The basis in futures has changed from-100 to -50, which means that the basis has become larger or smaller? Does the weakening of basis mean that the absolute value becomes smaller or the numerical value becomes smaller?
This should be divided into forward market and reverse market. For example, in the forward market, the futures price is higher than the spot price by 100 yuan, and the basis is the spot minus futures =- 100. If the spot price rises, the futures price remains unchanged, the spot price rises by 50 yuan, and the basis becomes -50, which means that the basis becomes smaller and the absolute value changes!
