Rounding Bottom

Definition of 'Rounding Bottom'


A chart pattern used in technical analysis, which is identified by a series of price movements that, when graphed, form the shape of a "U".

This pattern's time frame can vary from several weeks to several months and is deemed by many traders as a rare occurrence.

Investopedia explains 'Rounding Bottom'


A rounding bottoms look similar to the cup and handle pattern, but does not experience the temporary downward trend of the "handle" portion. The initial declining slope of a rounding bottom indicates an excess of supply, which forces the stock price down. The transfer to an upward trend occurs when buyers enter the market at a low price, which increases demand for the stock. Once the rounding bottom is complete, the stock breaks out and will continue in its new upward trend.
