Answer:
The correct word for the blank space is: risk.
Step-by-step explanation:
Risk is something that most investors try to avoid. The riskier an asset is, the more return it should make up for taking the risk. Investment risk is measured through something called the Standard Deviation. It is a calculation of how high and low an asset's price falls compared to its average price.
For easier understanding and assessment, risk can also be defined as the vulnerability of the asset on changes over the time it is under possession -time horizon- minus the risk the asset currently has. Uncertainty should be added, as well.
