Asset classes

An asset class is a group of instruments which have similar financial characteristics and behave similarly in the marketplace. We can often break these instruments into those having to do with real assets and those having to do with financial assets. Often, assets within the same asset class are subject to the same laws and regulations; however, this is not always true. For instance, futures on an asset are often considered part of the same asset class as the underlying instrument but are subject to different regulations than the underlying instrument.

Many investment funds are composed of the two main asset classes which are securities: equities (stocks) and fixed-income (bonds). However, some also hold cash and foreign currencies. Funds may also hold money market instruments and they may even refer to these as cash equivalents; however, that ignores the possibility of default. Money market instruments, being short-term fixed income investments, should therefore be grouped with fixed income.
