摘要：
Empirical evidence of a multifractal signature during increasing of a financial bubble leading to a crash is presented. The April 2000 crash in the NASDAQ composite index and a time series from the discrete Chakrabarti-Stinchcombe model for earthquakes are analyzed using a geometric approach and some common patterns are identified. These patterns can be related the geometry of the rising period of a financial bubbles with the non-concave entropy problem. (C) 2012 Elsevier B.V. All rights reserved.
