Investing always involves certain risks, and understanding these risks is a key aspect of successful portfolio management. In this article, we will look at the main types of risks investors face and how to manage them.

Systematic and unsystematic risk:
Systematic risk, also known as market risk, is related to general factors affecting the entire market environment such as economic conditions, political instability, inflation, etc. This risk cannot be completely eliminated, but can be managed through portfolio diversification and the use of hedging instruments such as futures and options.

Unsystematic risk, also known as specific risk, relates to specific factors affecting a particular company or industry. These include operational risks, financial risks, industry competition risks, etc. This type of risk can be mitigated by diversifying the investment portfolio, i.e. allocating funds across different companies, industries and assets.

Yield and liquidity risk:
Yield risk relates to potential changes in investment returns due to factors such as changes in interest rates, inflation, exchange rate fluctuations, etc. This risk can be managed by selecting appropriate investment instruments and diversifying the portfolio.
Liquidity risk refers to the possibility of being unable to sell investments quickly without significant loss of value. Management of this risk involves proper planning and consideration of liquidity of various assets in the portfolio.

Psychological risk:
Psychological risk relates to investors' emotional reactions to market fluctuations. Fear, greed and euphoria can lead to rash decisions and capital losses. Managing this risk involves developing disciplined trading strategies, setting clear rules and following an investment plan.

In conclusion, understanding the main types of risks and how to manage them is an important step towards successful investing. Investors should be prepared for a variety of risks, but proper risk management can help them protect their capital and achieve their financial goals over the long term.
