How to reduce the risk of your investment portfolio? The simplest way is diversification. It means the purchase of shares of various companies from several sectors and countries. However, the shares of Aeroflot, Magnit, and several other Russian companies do not at all indicate that you have collected a reliable portfolio. These issuers directly depend on the state of the Russian economy: if the incomes of Russians decrease, then you, as a shareholder, will also earn less. We will tell you how diversification will help to competently assemble an investment portfolio.
