How can market sentiment affect liquidity?

Market sentiment plays a crucial role in determining liquidity because it reflects the overall attitude of investors toward market conditions and economic factors. When market sentiment shifts—whether it be optimistic or pessimistic—it can lead to rapid changes in how participants behave in the market.

For instance, during periods of positive sentiment, investors may be more willing to buy securities, which can increase demand and enhance liquidity. Conversely, negative sentiment can trigger panic selling or a flight to quality, causing many investors to sell off assets simultaneously. This sudden rush can create a situation where the market experiences decreased liquidity as the number of willing buyers diminishes, leading to wider bid-ask spreads and a potential misalignment between supply and demand.

Thus, the correct answer emphasizes that fluctuations in market sentiment can directly influence liquidity through the behavior of investors, causing catalyzed movements in market activity that may lead to either enhancing or constraining liquidity based on prevailing attitudes.
