In order to help investors assess the credit worthiness of an obligor, independent nationally recognized statistical organizations, also called rating agencies, offer appraisals of the financial stability of a particular issuer and its ability to pay income and return principal on an investment.Moody’s, S & P and Fitch are the better known rating agencies that assign a specific rating indicating the degree of risk an investor acquires by owning debt in a particular obligor’s name.
This is an obligor’s inability to remain solvent and pay any outstanding debt obligations in a timely manner. Adverse changes in the creditworthiness of the issuer (whether or not reflected in changes to the issuer’s rating) can decrease the current market value and may result in a partial or total loss of an investment.
Occurs as interest rate changes occur. The yield offered on bonds is based upon a collaboration of all associated risks evaluated, coupled with a market determined spread over a similarly traded riskless transaction (historically measured versus a similar maturity Treasury bond). As interest rates fluctuate, the yield on most bonds will be adjusted accordingly. Generally, as interest rates rise, the price of a bond will fall and conversely, as interest rates fall, the price of a bond will rise.
Timing of reinvestment of returning interest or principal can cause an investor’s return to fluctuate. In a falling interest rate environment, an investor will likely benefit from higher coupons and longer maturities as this prevents the need to reinvest into a lower, less favorable interest rate environment. If interest rates are rising, higher coupon and/or short maturities allow an investor to take advantage of rate increases and put their money to work at improving interest rates.
