Checked the book -- I'm not sure why I remembered that it "opened"
with that -- it doesn't at all, maybe it was just the first bit I
read.

Stock market data are used in two places: as an illustration of time
aliasing resulting from decimation in the frequency domain (take an
8192-point DFT of 27 years of Dow closings, take only every 8th point,
inverse DFT: observe to general amazement that the result is nothing
like the original), and in a separate exercise in stochastic
modelling.
