How to calculate Yield to Maturity in CASIO FC-200V Calculator?
There is an option called "BOND" in this specific calculator, but it doesn't give the right YTM in bonds that are inflation-linked. For example:  An inflation-linked bond bought on 03/12/2018. Base Index: 83.4. Known Index: 101.8. Coupon: 4.1% Annually, paid once a year. The nearest payment day: 29/03/2019. Date of redemption: 29/03/2021. The principle is paid by 3 equal payments. In Excel it pretty simple to calculate, and the yield comes out right, 0.58%. But in the calculator, it just comes out negative 2%, (-2%). I've tried to do it with dates or with terms, I tried to deduct the inflation both for the price and for the "RDV" (redemption value). It always negative.
