I don't construct factor models or do any of the dirty work, i choose what signals to take from pairtrade finder and then manage the trade myself, the rok/wy trade has gone against me quite some atm, as ive discussed previously i added a correlation filter to my signals to make sure i only take trades on increasing correlation which rok & wy didn't have. position trading is my main game, pair trading is something ive branched into in the last several months, and there have been some qualitity insights in this thread from a few experts, so i'm constantly tweaking & adjusting my trading plan as I learn, the past couple of weeks have taught me a lot and how well risk management deals with the unknown.
Quote from lolatency:
I was reviewing your ROK/WY trade. I'm trying to figure out if you are calculating correlation by raw prices or returns of prices.
I don't understand what in the real world this correlation represents. Do you construct factor models to regress against the indices and then take the correlation of the resulting residuals? If there's no news driven activity on the two stocks, how do we know that the correlation between the two stocks isn't just due to moving with the major indexes?
Can we review your reasons for this trade, what your signal was, when and why? Just as a learning exercise?
If the tone of my post sounds critical, pardon me -- it's not. I'm trying to understand your methodology.
