The curves of multifractal fluctuation functions Fq(s) to s in the log–log plot, Generalized Hurst exponents h(q), Mass exponent and multifractal spectra for the aggregate and sectoral indices during the GFC period. Note: Fq(s) indicates variation in the fluctuation of series for various orders across various time segments. h(q) indicates the scaling exponent which is the slope of the regression for log(Fq(s)) to s. τ(q), calculated as qh(q)-1, is multifractal exponents which have a nonlinear structure if the series follows a multifractal structure. f(α), called as singularity spectrum, indicates the fractality dimension of the subperiod related to the series
