The difference between (e) and (f) suggests that real returns of DJIA are not fully described by a pure random walk.
In linear scale (not shown), the growth is exponential, with very rapid growth in the last three decades. 1(b), the daily logarithmic returns are shown. 3) Large variations are visible especially during major market corrections and crashes such as 1929, 1987, and 2008. Another noticeable feature is the clustering of variability (also linked to volatility or variance of returns). 2 shows the normal probability plot of daily logarithmic returns of DJIA, r, as defined above. The dotted line corresponds to a normal distribution, while the solid curve corresponds to calculated daily returns from DJIA data.
