Testopedia explains Nonsystematic Risk
Often times the value of an investment will fluctuate with the market as a whole. If the market is generally declining the value of an investment may decline simply because the market as a whole is falling. This is known as systematic risk. Other times an investment may loss value as a result of problems with a specif company or industry. When the Government sued the tobacco companies or when a company faces a major issue these would be examples of non systematic risk. An investor may diversify out of non systematic risk.
