I don't think that beta by itself will lead me to AIMable stock choices. I know far better than to think that any one thing will. But, that said, it is a factor, in volatility it seems, which is a factor, though admittedly not the only one or even the most significant one.
If it is a factor, as it seems it is, I simply want to fully and accurately understand it and be able to compare apples to apples.
