Maybe I don't understand the term, but don't you mean they're distributed? How are they correlated, unless you can identify some pattern in the results?

H = # of heads
T = # of tails

If you flip a coin ten times,

H = 10 - T

i.e., given one you know the other, so they are perfectly correlated. This is a simplistic example of two observables (H and T) that are 100% correlated yet random. One can contrive far more complicated and subtle examples illustrating the same principle.

I'm not following this thread carefully enough to know how relevant this point is to the issue being discussed, but I get nervous when I read something like "Correlation is the mathematical measurement of randomness. If you have correlation, you don't have randomness."

I have no opinion on the randomness vs. non-randomness of the stock markets. I have every faith in my inability to predict their movements.
