Mispricing is the difference between the actual value of a security and its market price. It occurs when the market incorrectly values a security due to incorrect information or lack of information.

Mispricing is a term used to describe the phenomenon of a security or asset being traded at a price that does not accurately reflect its true value. This can occur for a variety of reasons, including market inefficiencies, investor sentiment, and information asymmetry. Mispricing can be either positive or negative, meaning that a security may be overvalued or undervalued.
Positive mispricing occurs when a security is trading at a price higher than its true value. This can be caused by investor sentiment, which can lead to a “bubble” in the market. This can be seen in the stock market, where investors may become overly optimistic about a particular stock and drive up its price beyond what is justified by its fundamentals.
Negative mispricing occurs when a security is trading at a price lower than its true value. This can be caused by market inefficiencies, such as when investors are not aware of all the information available about a security. It can also be caused by information asymmetry, which occurs when one party has more information than another.
Mispricing can have a significant impact on the performance of a portfolio. If a security is mispriced, it can lead to either an overvaluation or an undervaluation of the portfolio. This can lead to either an over- or under-performance of the portfolio relative to its true value.
In order to avoid mispricing, investors should be aware of the factors that can lead to mispricing and take steps to ensure that their portfolios are accurately valued. This can include conducting thorough research on the securities in their portfolio, monitoring market conditions, and diversifying their investments. Additionally, investors should be aware of the potential for mispricing and be prepared to adjust their portfolios accordingly.
