unsystematic risk การใช้

• Unsystematic risk falls into two categories.
• Synonyms for diversifiable risk are idiosyncratic risk, unsystematic risk, and security-specific risk.
• In fact, most unsystematic risk is removed by holding a portfolio of about twenty-five to thirty securities.
• Public capital markets do not provide evidence of unsystematic risk since investors that fail to diversify cannot expect additional returns.
• In addition to systematic risks, the discount rate must include " unsystematic risk " representing that portion of total investment risk that can be avoided through diversification.
• The other category of unsystematic risk is referred to as " company specific risk . " Historically, no published data has been available to quantify specific company risks.
