Risk management is the process of identifying, assessing and controlling threats to an personal or organization's capital and earnings.
These threats, or risks, could stem from a wide variety of sources, including financial uncertainty, legal liabilities, strategic management errors, accidents and natural disasters.
Knowledge of type of risk we can face is important so that we can diversify that risk. Because not all risk can be diversified, so for those we hedge our risk.
Sometimes we take more risk without our knowledge for the same return like in MF investment or new business projects.
