Sector Breakdown of Diversified Portfolios
In a recent column, The Globe & Mails Rob Carrick (see Beware the limitations of buying the index, May 11, 2012) pointed out that investing in just the TSX Composite index might leave an investor with an unbalanced portfolio because of the indexs concentration in just three sectors: financials, energy and materials. The criticism is a valid one because, as you can see from the chart below, resource companies make up more than half the index and financials make up another one-third of the index. (As an aside, the sector breakdown of the S&P/TSX 60 index, which is tracked by the iShares S&P/TSX 60 ETF TSX: XIU is pretty much the same as the broader Composite index).

This limitation of the TSX Composite Index is one reason why passive investors diversify their portfolios globally. The US Total Stock Market, for instance, offers much better diversification. The three dominant sectors in the Canadian market make up less than a third of the US stock market.
