Target market

This circle-spoke diagram sample illustrates the target market concept.
"A target market is a group of customers towards which a business has decided to aim its marketing efforts and ultimately its merchandise. A well-defined target market is the first element to a marketing strategy. The marketing mix variables of product, place (distribution), promotion and price are the four elements of a marketing mix strategy that determine the success of a product in the marketplace." [Target market. Wikipedia]
The hub-and-spoke diagram example "Target market" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Circle-Spoke Diagrams solution from the area "What is a Diagram" of ConceptDraw Solution Park.

This inverted pyramid diagram of global liquidity shows world GDP and liquidity for 4 levels: derivatives, securitised debt, broad money, and power money.
"In business, economics or investment, market liquidity is a market's ability to facilitate an asset being sold quickly without having to reduce its price very much (or even at all). Equivalently, an asset's market liquidity (or simply "an asset's liquidity") is the asset's ability to sell quickly without having to reduce its price very much. Liquidity is about how big the trade-off is between the speed of the sale and the price it can be sold for. In a liquid market, the trade-off is mild: selling quickly will not reduce the price much. In a relatively illiquid market, selling it quickly will require cutting its price by some amount.
Money, or cash, is the most liquid asset, because it can be "sold" for goods and services instantly with no loss of value. There is no wait for a suitable buyer of the cash. There is no trade-off between speed and value. It can be used immediately to perform economic actions like buying, selling, or paying debt, meeting immediate wants and needs.
If an asset is moderately (or very) liquid, it has moderate (or high) liquidity. In an alternative definition, liquidity can mean the amount of highly liquid assets. If a business has moderate liquidity, it has a moderate amount of very liquid assets. If a business has sufficient liquidity, it has a sufficient amount of very liquid assets and the ability to meet its payment obligations." [Market liquidity. Wikipedia]
