| Abstract: |
Recent developments in the field of biophysics, both in findings and methods, have consequences that extend not only into physics in general, but may have application in a rigorous mathematical analysis of financial markets. Specifically, we apply the interpretative power of the Detrended Fluctuation Analysis to an Exchange Traded index Fund (ETF) mirroring the S&P 500. Not only do we verify the observation of positive long-range correlations, but we also characterize the effects of bin size on the DFA output. As a final application, we briefly examine the possibilities of using the results of a localized DFA to assess a measure of corporate health. |
