An estimate of the low moment values of the assumed multifractal spectrum of
Gold price, Dow Jones Industrial Average (DJIA) and Bulgarian Lev - USA Dollar
(BGL-USD) exchange rate over a 6
1/2 year time span has been made. The
findings can be compared to the analysis made on 23 foreign currency exchange
rates by Vandewalle and Ausloos but there is a clear indication of some
differences. Comparison to fractional Brownian motion is made. The analysis
shows that these three financial data are not likely fractal but rather multifractal
indeed.
