Benchmarks

 Outstanding nominal value as of the current date

Average price of a bond, in % of face value

The current yield indicates the ratio of the accrued coupon to the current market price of the bond. It can be used in cases where attachments are considered for a short period of time. In this situation, the change in the market price can sometimes be neglected.

Bond duration is a way of measuring how much bond prices are likely to change if and when interest rates move.

Effective yield to maturity. It considers both coupon income and profit/loss due to the difference between the purchase price and the repayment price. Effective yield shows the investor the return on invested funds with reinvested coupons and depreciation.

Listing level — stock exchange assessment of securities reliability.

The ratio of the annual coupon to the "dirty" price of the bond, including the accrued interest. This type of yield can be used in the case of short-term investments, when the investment horizon is within one coupon period.

Average purchase price of a bond, in % of face value

Bond issue credit ratings from ACRA / Expert RA rating agencies. The higher the rating, the lower the estimated credit risk. A rating is not a guarantee and does not replace your own analysis.
