Bond prices are more affected by ratings changes. The effect on stock prices is mixed (e.g., a downgrade can produce a higher stock price).

2、Which of the following statements is TRUE?

A) Technical default usually refers to the issuer's failure to make interest or principal payments as scheduled in the indenture.

B) When a rating agency downgrades a security, the bond's price usually falls.

C) Default risk is important because if a bond issuer defaults, the bondholder likely loses his entire investment.

D) Bond ratings are determined by the market.

aianjie

 

The correct answer is B

The market will likely demand a higher yield from the downgraded bond (the risk premium has increased) and thus the price will likely fall. Technical default usually refers to an issuer’s violation of bond covenants, such as debt ratios, rather than the failure to pay interest or principal. In the event of default, the holder (lender) may recover some or all of the investment through legal action or negotiation. The percentage recovered is known as the recovery rate. Rating agencies such as Moody’s and Standard and Poor’s assign bond ratings. The market reflects these ratings through a higher or lower market yield.

3、Six months ago an investor purchased a bond that was rated BB. Today the bond is upgraded to a BBB rating. The most likely effect of this upgrade is:

A) an increase in yield to maturity.

B) increased liquidity risk.

C) increased call risk.

D) a higher spot price.

aianjie

 

The correct answer is D

An increase in spot price is the most likely effect of an upgrade. This higher price will lead to a decrease in YTM. Liquidity risk will be lower as the bond will now be classified as an investment grade bond, and therefore would be an allowable investment for an increased number of pension plans and mutual funds. Increased call risk may be possible if the rating upgrade was due to an improved financial situation for the company, but without more information this cannot be determined.
