We also show that intermittency -- strong bursts in the energy dissipation or clusters of high price volatility -- and nonextensivity -- anomalous scaling of usually extensive properties like entropy -- are naturally linked by a single parameter q, from the nonextensive thermostatistics.LaTex file + 3 postscript figures, 9 pages, submitted to Europhysics LettersCondensed Mattertext
