      I did not say that at all!

      I said that in real life, investments are positively correlated and so risk cannot be removed (the systematic risk will remain) but that it can potentially be reduced.

      Ice cream and umbrella was an extreme example where they were perfectly negatively correlated that does not occur in real life.

      From the previous lectures, Tutor has clearly explained that when the standard deviation increases the risk also increases. Standard deviation is the measure of risk itself. Am I right admin? Correct me if I am wrong :) ?
