Re: New pair trade - Long RIO / Short BHP

no correlation is measuring the strength of the relationship between two stocks, for example the current correlation reading on BHP/RIO is 96.90% which means they are almost in lockstep with each other. the rolling mean is the numerical representation of the day to day relationship between BHP & RIO.

how do you find the correlation. is their any site for it?
