Which factors contribute to the specific risk of an investment?

The correct answer highlights how both the rate of corporate taxes and fraud by senior management specifically affect the risk associated with an individual investment.

Specific risk, also known as unsystematic risk, pertains to risks that are unique to a particular company or industry. The rate of corporate taxes can significantly influence a company’s profitability and cash flow, thereby impacting its overall financial health and investment appeal. An increase in corporate taxes can erode profits, making the company less attractive to investors and potentially lowering its stock price.

Fraud by senior management represents a severe risk that can lead to significant financial misstatements, loss of investor confidence, and even legal consequences for the company. Such actions can dramatically affect the company's stock price, as investors assess the likelihood of future earnings and the integrity of the management team.

In contrast, financial leverage, market volatility, and interest rate changes fall under systematic risk, which affects all investments across the market rather than affecting a specific company or industry. While financial leverage can influence the potential return on investment, it does not constitute specific risk since it is a general characteristic seen in many companies. Similarly, market volatility and interest rate changes are more relevant to the broader economic environment and impact overall market trends rather than individual investment risk.
