Risk = concerns the expected value of one or more results of one or more future events. Technically, the value of those results may be positive or negative. However, general usage tends focus only on potential harm that may arise from a future event, which may accrue either from incurring a cost (“downside risk“) or by failing to attain some benefit (“upside risk“).

Return = rate of return (ROR), also known as return on investment (ROI), rate of profit or sometimes just return, is the ratio of money gained or lost (whether realized or unrealized) on an investment relative to the amount of money invested. The amount of money gained or lost may be referred to as interest, profit/loss, gain/loss, or net income/loss. The money invested may be referred to as the asset, capital, principal, or the cost basis of the investment. ROI is usually expressed as a percentage rather than a fraction.

Currency = In economics, the term currency can refer either to a particular currency, for example the US dollar, or to the coins and banknotes of a particular currency, which comprise the physical aspects of a nation’s money supply.

Equities = The stock or capital stock of a business entity represents the original capital paid or invested into the business by its founders. It serves as a security for the creditors of a business since it cannot be withdrawn to the detriment of the creditors. Stock is distinct from the property and the assets of a business which may fluctuate in quantity and value

Capital Asset Pricing Model = is used to determine a theoretically appropriate required rate of return of an asset, if that asset is to be added to an already well-diversified portfolio, given that asset’s non-diversifiable risk. The model takes into account the asset’s sensitivity to non-diversifiable risk (also known as systematic risk or market risk), often represented by the quantity beta (?) in the financial industry, as well as the expected return of the market and the expected return of a theoretical risk-free asset.

Risk-Return Profile = The degree to which various risks are important to a particular individual
