Because of what you said, "figuring out which stocks validly and
reliably respond to seasonal influences". That's why I said it's not

Hey, Jerry.:)
It's not clear to me why seasonality can't be coded into the method.
Other problems are clear, like figuring out which stocks validly and
reliably respond to seasonal influences (which sounds like a messy
research problem all by itself), but what's the coding difficulty?
