Which type of risk is not associated with investing in stocks?

Interest rate risk is indeed not typically associated with investing in stocks in the same way it is with fixed income securities like bonds. Stocks represent ownership in a company and their value is primarily determined by the company's performance, market demand, and economic conditions, rather than directly by changes in interest rates.

Market risk, on the other hand, pertains to the volatility and fluctuations in the overall market that can affect stock prices regardless of the individual company's performance. Similarly, industry risk involves factors that can impact entire sectors or industries, which could lead to declines in stock values within that sector.

The risk of loss of principal is an inherent part of investing in stocks because the value of stock investments can decrease, resulting in the potential for losing the original amount invested. Thus, while stock investments do carry various types of risks, interest rate risk primarily pertains to fixed-income securities and is less relevant to the stock market, making it the correct answer in this context.
