Additionally, the iShares Core ETFs provide annual expense ratios of 0.07% to 0.18%.

The iShares Core ETFs include:

  • iShares Core S&P 500 ETF (NYSEArca: IVV)
  • iShares Core S&P Mid-Cap ETF (NYSEArca: IJH)
  • iShares Core S&P Small-Cap ETF (NYSEArca: IJR)
  • iShares Core S&P Total U.S. Stock Market ETF (NYSEArca: ITOT)
  • iShares Core MSCI Emerging Markets ETF (NYSEArca: IEMG)
  • iShares Core MSCI EAFE ETF (NYSEArca: IEFA)
  • iShares Core MSCI Total International Stock ETF (NYSEArca: IXUS)
  • iShares Core Total U.S. Bond Market ETF (NYSEArca: AGG)
  • iShares Core Long-Term U.S. Bond ETF (NYSEArca: ITLB)
  • iShares Core Short-Term U.S. Bond ETF (NYSEArca: ISTB)

Rawson believes that a diversified core portfolio of ETFs only requires three out of the 10 holdings: ITOT at 30%, IXUS 30% and AGG 40%. This would create a basic 60/40 stocks/bonds investment portfolio with a weighted average expense ratio of 0.10%. Historically, the hypothetical portfolio of ITOT, IXUS and AGG would have returned 6.5% per year over the last 15 years.
