Zorluk: OrtaNon-Systematic and Credit Risks

A pharmaceutical firm experiences an unexpected failure in a key clinical drug trial, prompting credit rating agencies to downgrade the firm's debt and causing a steep decline in its stock price. A financial advisor reviews the impact of this event on client portfolios. Which of the following statements regarding the risks illustrated in this scenario are correct?

  1. The sharp decline in the issuer's bond and equity values stems from business and credit risk, which are forms of non-systematic risk.Cevap
  2. An investor can substantially mitigate this specific form of risk by allocating capital across a broadly diversified portfolio of un-correlated securities.Cevap
  3. C
    The primary cause of the bond's price decline in this scenario is market interest rate risk, which impacts all debt instruments equally regardless of credit rating.
  4. D
    Because clinical trial outcomes reflect broader economic conditions, the resulting security losses represent market risk that cannot be diversified away.

Cevap

The decline in security values stems from business and credit risk (non-systematic risks specific to the issuer), and this type of risk can be substantially mitigated through portfolio diversification.
The correct statements recognize that company-specific operational failures (such as clinical trial outcomes) and debt downgrades represent business and credit risks, which are non-systematic in nature. Furthermore, non-systematic risks can be effectively managed and reduced through asset diversification across multiple issuers and business sectors.

Adım Adım Çözüm

1
Identify the nature of the risk event described in the scenario.
The failure of a clinical trial and subsequent downgrade of a single company's debt are issuer-specific events.
Events tied directly to a specific company's operational outcomes or creditworthiness represent non-systematic risk (business risk and credit risk).
2
Determine how non-systematic risk behaves within a portfolio context.
Non-systematic risk affects specific issuers rather than the entire financial system.
Because non-systematic risks are uncorrelated across different industries and issuers, holding a diversified portfolio dilutes issuer-specific losses.
