Appreciate the comments b.o.g...not refuting anything you're saying but the skeptic in me thinks this feels like a big curve fitting exercise. My two responses below are what would nag at me at if considering adding something like this to my set of models.
Sounds spurious and unpredictable.
Exactly...screw around with pairings and ratios long enough and you will certainly find perfectly mean reverting and/or trending combinations - historically. Without an intuitive reason for why that existed/should continue, it doesn't pass the sniff test (for me). In my trading, it's rare to have anything work out of sample unless I have a good reason for the anomaly to begin with.
I'm not knocking bone's services at all - just some concerns I'd have about any non-arbitrage approach to pairs. In fact, if he has good answers to the above, I'd consider contacting him.
what he says is true that when you have correlated products, for some reason they have moments where you can get some clean trends.
Sounds spurious and unpredictable.
the truth is, any bonehead can purchase and autospreader and play around with various products. The key is do you have an idea as to why the strategy would exist in the first place, you just have to work hard to manipulate data and play around with combinations........
