I came across the following table showing the sector weightings in the MSCI Emerging Markets Index and select developed market indices:

Note: The data shown above are as of Dec, 2016. So the weightings may have changed since then.

Some of the high-level observations from the above are:

• Canada’s TSX Composite index is heavily concentrated in financials followed by energy and materials.
• Emerging markets are also dominated by Financials. On the other hand the US index has about 15% in financials.
• The tech sector accounts for about one-fifth of the S&P 500 but the EAFE and TSX indices have low tech sector weightings. It is surprising that the sector is the 2nd largest sector in the emerging markets index.
