Which group of users is primarily concerned with the risk and return of investments?

The group of users primarily concerned with the risk and return of investments is investors. Investors focus on the performance of their financial holdings, assessing the potential for capital appreciation and income generation. They analyze various factors such as market trends, historical performance, and economic conditions to make informed decisions regarding their investment portfolios.

Investors are often interested in understanding risk profiles because they want to gauge the potential hazards that might impact their investments' value. They are also focused on measuring returns called yields or profitability, ensuring that the rewards justify the risks involved. This evaluation is crucial for maximizing investment performance and achieving financial goals.

In contrast, other groups mentioned have different priorities: employees are more focused on job security and compensation, suppliers seek timely payments and stable purchasing arrangements, and customers are primarily concerned with product quality and service. Each group has its unique interests in a company's operations, but none of them is primarily focused on investment risk and return like investors are.
