My recollection is that Pearson's r assumes a normal distribution
of
values. Remember that trends and price changes often do not behave
in
accordance with a normal distribution -- just ask the
Long-Term
Capital Management guys.

Subject: [RT] near a bottom
I
have been working on a strategy that uses the Pearson r
Correlation
Coefficient as a means of estimating points of Change In
Trend.
The attached picture is of 30 minute bars of ES. You will
notice that
in this scenario the CIT has been fairly well
called.
That is said to note that the strategy called for the trend to
turn
positive in the middle of the day -- so maybe near bottom ! !
