Flight to liquidity means that investors seek out investments that can be sold quickly and easily and for a good price in order to get money back quickly. Imagine you have $10. You can buy a toy train that takes a long time to build. But if you need your money back right away, you would want something more liquid, like a can of Coke. The can of Coke can be quickly traded, and you can easily get your $10 back. Investors do the same thing in the stock market. They look for investments that can be sold quickly and easily, and for a good price, so they can get their money back when they need it.
