Definition of 'Overbought'
1. A situation in which the demand for a certain asset unjustifiably pushes the price of an underlying asset to levels that do not support the fundamentals.
2. In technical analysis, this term describes a situation in which the price of a security has risen to such a degree - usually on high volume - that an oscillator has reached its upper bound. This is generally interpreted as a sign that the price of the asset is becoming overvalued and may experience a pullback.
Investopedia explains 'Overbought'
1. An asset that has experienced sharp upward movements over a very short period of time is often deemed to be overbought. Determining the degree in which an asset is overbought is very subjective and can differ between investors.
2. Technicians use indicators such as the relative strength index, the stochastic oscillator or the money flow index to identify securities that are becoming overbought.
An overbought security is the opposite of one that is oversold.
