Risk can be defined is likelihood of occurrence of losses relative to the expected return on any particular investment.
Risk is an important component in assessment of the prospects of an investment. Most investors while making an investment consider less risk as favorable. The lesser the investment risk, more lucrative is the investment. However, the rule of thumb is the higher the risk, the better the return.
Unfortunately, there is no magic wand or formula that will remove risk from investments or financial vehicles. There will always be some form of risk involved when trying to grow money.
The issue is then to reduce and or remove as many risk factors as possible. The other is to recognize what actually contributes to risk and how much control you have over it.
