ETFs with More Assets May Be Best

For large-cap growth, there is the iShares 1000 Growth Index Fund(IWF) and the iShares S&P 500 Growth Index Fund(IVW). On the value side of large cap, there is the iShares 1000 Value Index Fund(IWD) and the iShares S&P 500 Value Index Fund(IVE).

Similarly broad representation is available in the table for small cap and mid cap investments.

International representation varies from the broad geographic coverage of the iShares MSCI EAFE Index Fund(EFA) to the subcategory of emerging markets -- the iShares MSCI Emerging Markets Index Funds(EEM) and the Vanguard Emerging Markets ETF(VWO) -- to other ETFs specializing in Japan, Brazil and China.

For fixed-income needs, the list contains a short-term Treasury fund, an inflation-protected Treasury fund and an investment grade general bond fund.

Sector funds in the table include gold and energy.

The large ETFs in the table have generally served their holders well by returning, on average, 8.88% over the 12 months ended Feb. 29. That compares with a negative total return of 3.60% for the S&P 500 total-return index, and an average of minus 1.44% for the ETFs that didn't make the biggest-25 list. Helping the largest of the breed was an average expense ratio of only 0.28%, which amounts to half the average levy extracted by the remaining ETFs.

The largest 25 ETFs also held closer in market prices to their respective NAVs, on average, than the remaining funds.

The ETFs in the table represent 59.9% of the total net assets of all ETFs.
