A multibagger stock is an equity stock which gives a return of more than 100%.
The term was coined by Peter Lynch in his 1988 book One Up on Wall Street and comes from baseball where "bags" or "bases" that a runner reaches are the measure of the success of a play.
[1] For example, a ten bagger is a stock which gives returns equal to 10 times the investment, while a twenty bagger stock gives a return of 20 times.
[2] This term is especially common when discussing high-growth industries and emerging markets such as the BRICS.
[3] As with most investment metrics, past performance is no guarantee of future returns, and multibag returns may be indicative of either sustained growth or an investment bubble.
