In order to get the benefit of minimising risk in a portfolio, we need to:

		Add assets to our portfolio that move in the same direction to the assets in our portfolio.
		Add assets to our portfolio that have a correlation of +1 to the assets in our portfolio.
		Add assets to our portfolio that have a correlation of less than 1 to the assets in our portfolio.
		Add assets to our portfolio that have similar unsystematic risk to the assets in our portfolio.
