"God is my shepherd
So nothing shall I want
I rest in the meadows
Of faithfulness and love
I walk by the quiet waters
Of peace.
Shepherd me, O God
Beyond my wants
Beyond my fears
From death into life."
Marty Haugen, Shepherd Me O God (Psalm 23)
“Some economists, when thinking about long memory, are concerned that it undercuts the Efficient Market Hypothesis that prices fully reflect all relevant information; that the random walk is the best metaphor to describe such markets; and that you cannot beat such an unpredictable market. Well, the Efficient Market Hypothesis is no more than that, a hypothesis. Many a grand theory has died under the onslaught of real data.” Benoît B. Mandelbrot
