Andrew,
Interesting thought. I'm doing quite a bit right now with volatility
-- for setup, entry, exit and money management -- and had not thought
of this.
The result of normalizing the RS using beta or atr would suggest a
"risk adjusted" metric for comparing one security's RS against another's.
I'm not sure if that is worthwhile. I like to know the "raw" RS first.
Then I do my "risk adjustments" (i.e. volatility-based position sizing
and money management stop placement) as a next step. Merging these two
steps might fail to highlight some high RS/high volatiltiy (but
promising) candidates?
