Pro Forma Portfolio 2 shows greater partiration in the 1- an3-yematurities relative to the current portfolio anthe least combineexposure in the 10- an30-yematurities of the three portfolios. The prectechange is calculatefollows: Prectechange = Portfolio pamount × partiPV× (curve shift in bps)/100老师您好，拿到这个题应该从哪里入手，考的哪个考点，谢谢🙏
