WHen the algos are programmed, does anything matter?
But, I guess the old Algos should be modified timely manner today ... when math-lover or Quants, like renaissance 's Mr. Simons, started the algo, and most so-called fund mgrs not so familiar with HFT, well you could be little lazy ... but, nowadays all the rednecks are good at algos. So, you can't be lazy anymore I guess. You should move some factors more frequently notch by notch, aren't you ?
Why make the world so complicated ? The results might be the same. "The survival of the fittest." won't be changed anyway. Don't make it complicated. :)
