Quote from PIZZAPIZZA:
money with all this journal talk.
If you dont have this pair in your inventory, check it out. CFR and PRSP - both are strong high quality texas regional banks. On a simple term - when one moves 4 to 6 percent on the other, go against it. You can run all the other data and testing you want on it to get at a more statistical signal, but the end result will be a signal triggered about the same time.
The only real divergence was in 2/08 due to an adjustment related to earnings.
Both have great asset quality, but if one erodes relative to the other after earnings (npa/ta), be careful to see if the correleation fades. If not, its easy money over and over.
Another great pair is knx/htld. To short-to-medium haul trucking stocks. Triggers seems to manifest near the dollars, but id wait for 6 to 10 percent moves to fade or begin ranging into it slowly.
