Explanation:

Portfolio risk is a term used to describe which chances of combining assets or units fail to meet the objectives you had when you established some type of investment. The greater the economic return that an investment offers, the greater the portfolio risk will be and more losses may be presented.

However, the portfolio risk can be reduced in high-risk investments, if a diversification of incest combinations is established that does not depend on just one factor, to be successful. However, due to the effects of diversification, the portfolio's risk is likely to be higher than the average of the standard deviations of all stocks. In this case, the risk of a portfolio is likely to be less than the average of the standard deviations of all stocks, because diversification reduces the risk of the portfolio.
