What to correlate with a large cap financial

[Mark Jackson <maj@xxxxxxx>]

I am trying to develop a system to track a large cap diversified company
that seems to act more like a financial company than anything else.
Stock indexes can't serve as much of a leading indicatior because of the
large effect it has on the weighting of most of those indexes.  I am
wondering what I might look at  in the way of a relationship with 30
bond prices.  I am very unfamiliar with the futures market.  What about
tracking the price trend on 30 year T-bond futures on the same time
frame as I am tracking my equity?  Can someone give me some pointers me
on the use of T-bonds for this prupose?  Thanks  M Jackson maj@xxxxxxx
