It could be better.
For instance, today, just for fun, I was trying to find Statistics Canada data on Canadian investments. Other than general statistics on foreign investment, Statistics Canada has no information on which sectors Canadian companies invest in or how many of them are in China. That information is hard to find. We are talking about Statistics Canada.
I figure a private investor, or even an institutional one, doesn't know all that much more, except of course for information they can gather themselves from country or sector experts.
