Yuval,
I agree.
It is also my opinion that there is no need to avoid optimization. Optimization is not the same as overfitting. Your methods are similar (if not the same) as many widely used methods to avoid overfitting even while optimizing, I believe.
Not only do I agree but I do some things that I think are similar (in my own way).
I wonder if it would attract any members to P123 to be able to automate the optimization of 36 ranking systems and universes with 100 nodes in some way.
How long does it take to develop and test 100 nodes? 100 nodes before you start to optimize the ranking system for 36 universes.
I understand that Marco is already working on attracting members (or at least one paying member) by working on this. So this is not a request. Not even a suggestions as, again, Marco is working on this (if I understand correctly).
Automated methods are already being developed at P123 and will be made available to some members. And eventual roll-out to everyone over time.
This may be true also. The designers that do not do this are having trouble beating their benchmarks.
Understandably, some are using the other excellent tools (and methods) available at P123. I, for example, am using books a lot now. I believe some methods of diversification can beat the SP500 with considerably less risk. Others use timing or fundamental analysis.
Best,
Jim
