liquid asset has some or more of the following features. It can be sold rapidly, with minimal loss of value, anytime within market hours. The essential characteristic of a liquid market is that there are ready and willing buyers and sellers at all times.

This is related to a market depth, where sometimes orders cannot strongly influence prices.

Another example is an asset such as large block of stock, the sale of which affects the market value.

Often investments in liquid markets such as the stock exchange or futures markets are considered to be more liquid than investments such as real estate, based on their ability to be converted quickly. Some assets with liquid secondary markets may be more advantageous to own, so buyers are willing to pay a higher price for the asset than for comparable assets without a liquid secondary market. The liquidity discount is the reduced promised yield or expected return for such assets, like the difference between newly issued U.S. Treasury bonds compared to off-the-run treasuries with the same term remaining until maturity. Buyers know that other investors are not willing to buy off-the-run so the newly issued bonds have a lower yield and higher price.[citation needed]
