expectations theory, liquidity theory, market segmentation theory, and preferred habitat hypothesis theory. 

Liquidity Theory: The Liquidity Theory explains how an increase in liquidity (the ease at which assets can be converted into cash) affects the demand for, and thus price of, those assets. According to this theory, when there is more money available people tend to invest more in risky investments because they believe they can always cash out quickly if needed.

Segmentation Theory: Market Segmentation Theory suggests that different groups within a market or economy may respond differently to changes in economic variables. For example, people with higher incomes may be less sensitive to fluctuations in inflation than people with lower incomes. Thus policies aimed at one group may have a greater effect on another.

Preferred Habitat Hypothesis Theory: The Preferred Habitat Hypothesis states that investors prefer certain types of securities or markets over others depending on their risk preferences and investment goals. This theory suggests that investors are drawn to certain markets due to factors such as past performance and familiarity with these securities/markets leading them to choose investments based on preference rather than solely focusing on potential returns.
