Absence of 1/f Spectra in Dow Jones Daily Price

The power spectra for the daily Dow Jones average, both the original series and the de-trended series, are calculated. The spectra are of the form 1/ fCi with a close to 2 instead of 1. Also studied is the distribution of daily price changes which is in-between an exponential and a power law function. With certain criterion, this result suggests that stock market activities may not be qualified...

The apparently irregular (nonlinear) fluctuations are selfsimilar as exhibited in inverse power law form for power spectra of temporal fluctuations. Inverse power law form for power spectra of fractal fluctuations in space or time is generic to all dynamical systems in nature and...
