An economic bubble (sometimes referred to as a speculative bubble, a market bubble, a price bubble, a financial bubble, a speculative mania or a balloon) is “trade in high volumes at prices that are considerably at variance with intrinsic values”. It could also be described as a trade in products or assets with inflated values.
