Re: Portfolio "Risk X-RAY" analysis ?
An issue worth consideration is that many funds only report at quarter end what they hold at that time, and some portion of that is "window dressing". Therefore the data you're compositing, even with a good composition tool, may or may not be very accurate.
I used to have this bee in my bonnet when I was a working lad about making decisions on data that wasnt necessarily accurate. I suppose you might get a pretty good look if your funds have low turnover and you run the analysis right after they release the data. Towards the end of the quarter with high turnover funds, I wouldnt make any sorts of decisions or draw any conclusions from an 'x-ray'.
Be fearful when others are greedy, and greedy when others are fearful. Just another form of "buy low, sell high" for those who have trouble with things. This rule is not universal. Do not buy a 1973 Pinto because everyone else is afraid of it.
