In finance, an asset class is a group of marketable financial assets that have similar financial characteristics and behave similarly in the marketplace. These instruments can be distinguished as either having to do with real assets or 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.
