What is an Asset Class?
Asset classes are groupings of investments with similar characteristics; structure, risk, and reward.
By grouping investments, it is easier to understand their absolute and relative returns.
There may be no correlation between asset classes; however, investors may rotate between them based on returns, capital markets conditions, or goals.
Others may diversify risk across asset classes.
What are the main Asset Classes?
Common asset classes are cash, fixed income, equities, FX, commodities, alternatives, and digital assets (it is common to list asset classes from lowest to highest risk).
Some asset classes are traded on a public exchanges or capital markets, while in others are private or over the counter (OTC) transactions.
