An economic bubble or asset bubble (sometimes also referred to as a speculative bubble, a market bubble, a price bubble, a financial bubble, a speculative mania, or a balloon) is trade in an asset at a price or price range that strongly deviates from the corresponding asset's intrinsic value.[1][2][3] It could also be described as a situation in which asset prices appear to be based on implausible or inconsistent views about the future.[4] Asset bubbles date back as far as the 1600s and are now widely regarded as a recurrent feature of modern economic history.
