The liquidity of an investment refers to its marketability, which is the ease with which the investment can be bought or sold in the market without significantly affecting its price. A highly liquid asset is one that can be quickly bought or sold with minimal price impact, while a less liquid asset may experience larger price fluctuations when trades are executed.
Liquidity is an important consideration for investors because it influences the ease of entering or exiting a position and can impact the overall cost of trading. Marketable securities are easily tradable in the market, and their prices are generally less sensitive to the size of the trade. In contrast, less marketable or illiquid investments may require more time and effort to buy or sell and may result in higher transaction costs.
