Market liquidity refers to:

Market liquidity is fundamentally about the ease with which assets can be bought and sold in a market without causing significant price changes. This concept captures how readily assets, such as stocks or bonds, can be converted into cash or other assets. When market liquidity is high, transactions can occur swiftly and with minimal impact on the asset price, enabling buyers and sellers to enter and exit positions effectively.

The ease of buying and selling assets reflects critical factors like the volume of trades, the number of active market participants, and the presence of market makers who facilitate transactions. In a highly liquid market, investors can execute trades quickly and at expected prices, which is essential for maintaining market efficiency. Thus, defining market liquidity as the ease of buying and selling aligns perfectly with its practical implications in financial markets, directly affecting investment strategies and risk management.
