Definition of Risk

Definition of Risk:
Risk is the potential that a chosen action or activity (including the choice of inaction) will lead to a loss (an undesirable outcome). The notion implies that a choice having an influence on the outcome exists (or existed). Potential losses themselves may also be called "Risks". Almost any human endeavor carries some risk, but some are much more risky than others

Risk means a probability or threat of damage, injury, liability, loss, or other negative occurrence that is caused by external or internal vulnerabilities, and that may be neutralized through preemptive action.
Risk means the fair of danger. Risk is always concern the capital loss. It is a measurable uncertainty.
According to Weston & Brigham, “Risk is the chance that some unfavorable event will occur.”
According to J. C. Van Horne, “Risk is defined as the variability of possible return from a project.”
Another definition is that risks are future problems that can be avoided or mitigated, rather than current ones that must be immediately addressed.

In other word, Risks are future problems that can be avoided or mitigated, rather than current ones that must be immediately addressed.
Financial risk is often defined as the unexpected variability or volatility of returns and thus includes both potential worse-than-expected as well as better-than-expected returns.
The related term "hazard" is used to mean something that could cause harm.
