Is there a good website or any other way (that doesn't involve huge amounts of data and number crunching) of finding which share is most negatively-correlated with a particular share (both within the FTSE100)
I'm thinking of doing a bit of elementary hedging. Without getting into lots of clever things like derivatives, CFD, options, warrants etc, I figure that if I have a large exposure to one share (e.g. employee shares), one way to offset such a risk would be to buy some of the shares which behave in an opposite manner.
