Definition of 'Oversold'
1. A condition in which the price of an underlying asset has fallen sharply, and to a level below which its true value resides. This condition is usually a result of market overreaction or panic selling.
2. A situation in technical analysis where the price of an asset has fallen to such a degree - usually on high volume - that an oscillator has reached a lower bound. This is generally interpreted as a sign that the price of the asset is becoming undervalued and may represent a buying opportunity for investors.
Investopedia explains 'Oversold'
1. Assets that have experienced sharp declines over a brief period of time are often deemed to be oversold. Determining the degree to which an asset is oversold is very subjective and could easily differ between investors.
2. Identifying areas where the price of an underlying asset has been unjustifiably pushed to extremely low levels is the main goal of many technical indicators such as the relative strength index, the stochastic oscillator, the moving average convergence divergence and the money flow index.
Oversold is the opposite of overbought.
