LONDON -- If the long-run return on the market is 9.4% (as researchers at Credit Suisse say), then investing in shares should be a no-brainer; however, all too often our portfolios don't seem to reflect that attractive performance.
This is partly because that 9.4% number is an average derived from 100 years of data. Picking various time periods within that 100 years gives very different outcomes -- and the market almost never actually returns 9.4% in any single year.
Needless to say, unless you're holding a market tracker, your portfolio could have dramatically different results than what the market experiences. If you own a disproportionate amount of winning shares, your returns could be significantly better than the market. On the other hand...

Similar to BHP, Rio Tinto's fortunes have tracked demand for metals and coal -- mainly from China -- over the past decade. As that country faces a potential transition in its economy, investors need to ask themselves: "How much higher will demand go?"
Given the time it takes to bring new mines into operation, the mining industry is characterized by boom and bust as supply first lags demand and then races ahead. It would appear the market thinks were heading into a bust cycle. What do you think?
