Summary I’m taking a look at IDLV as a candidate for inclusion in my ETF portfolio. The expense ratio is a little high relative to my cheap tastes, but certainly within reason. The correlation to SPY is low and based on reasonable trade volumes. Returns since inception have been fairly weak, but the measuring period is less than 3 years. The ETF might fit for my portfolio. I’m not assessing any tax impacts. Investors should check their own situation for tax exposure. Investors should be seeking to improve their risk adjusted returns. I’m a big fan of using ETFs to achieve the risk adjusted returns relative to the portfolios that a normal investor can generate for themselves after trading costs. I’m working on building a new portfolio and I’m going to be analyzing several of the ETFs that I am considering for my personal portfolio. One of the funds that I’m considering is the PowerShares S&P International Developed Low Volatility Portfolio (NYSEARCA: IDLV ). I’ll be performing a substantial portion of my analysis along the lines of modern portfolio theory, so my goal is to find ways to minimize costs while achieving diversification to reduce my risk level. What does IDLV do? IDLV attempts to track the total return (before fees and expenses) of the S&P BMI International Developed Low Volatility Index. At least 90% of the assets are invested in funds included in this index. IDLV falls under the category of “Foreign Large Blend”. Does IDLV provide diversification benefits to a portfolio? Each investor may hold a different portfolio, but I use (NYSEARCA: SPY ) as the basis for my analysis. I believe SPY, or another large cap U.S. fund with similar properties, represents the reasonable first step for many investors designing an ETF portfolio. Therefore, I start my diversification analysis by seeing how it works with SPY. I start with an ANOVA table: (click to enlarge) The correlation is excellent at 71%. I want to see low correlations on my international investments. Extremely low levels of correlation are wonderful for establishing a more stable portfolio. I consider anything under 50% to be extremely low. However, for equity securities an extremely low correlation is frequently only found when there are substantial issues with trading volumes that may distort the statistics. Standard deviation of daily returns (dividend adjusted, measured since April 2012) The standard deviation is great. For IDLV it is .7265%. For SPY, it is 0.7420% for the same period. SPY usually beats other ETFs in this regard, so a lower volatility level is very impressive. Because the ETF has fairly low correlation for equity investments and a low standard deviation of returns, it should do fairly well under modern portfolio theory. Liquidity looks fine Average trading volume isn’t very high, a bit over 50,000, but that also isn’t low enough to be a major concern for me. Mixing it with SPY I also run comparisons on the standard deviation of daily returns for the portfolio assuming that the portfolio is combined with the S&P 500. For research, I assume daily rebalancing because it dramatically simplifies the math. With a 50/50 weighting in a portfolio holding only SPY and IDLV, the standard deviation of daily returns across the entire portfolio is 0.6794%. With 80% in SPY and 20% in IDLV, the standard deviation of the portfolio would have been .7045%. If an investor wanted to use IDLV as a supplement to their portfolio, the standard deviation across the portfolio with 95% in SPY and 5% in IDLV would have been .7312%. Why I use standard deviation of daily returns I don’t believe historical returns have predictive power for future returns, but I do believe historical values for standard deviations of returns relative to other ETFs have some predictive power on future risks and correlations. Yield & Taxes The distribution yield is 3.17%. That appears to be a respectable yield. This ETF could be worth considering for retiring investors. I like to see strong yields for retiring portfolios because I don’t want to touch the principal. By investing in ETFs I’m removing some of the human emotions, such as panic. Higher yields imply lower growth rates (without reinvestment) over the long term, but that is an acceptable trade off in my opinion. I’m not a CPA or CFP, so I’m not assessing any tax impacts. Expense Ratio The ETF is posting .35% for a gross expense ratio, and .25% for a net expense ratio. I want diversification, I want stability, and I don’t want to pay for them. The expense ratio on this fund is slightly higher than I want to pay for equity securities, but not high enough to make me eliminate it from consideration. I view expense ratios as a very important part of the long term return picture because I want to hold the ETF for a time period measured in decades. Market to NAV The ETF is at a .23% premium to NAV currently. Premiums or discounts to NAV can change very quickly so investors should check prior to putting in an order. The ETF is large enough and liquid enough that I would expect the ETF to stay fairly close to NAV. Generally, I don’t trust deviations from NAV and I will have a strong resistance to paying a premium to NAV to enter into a position. Largest Holdings The diversification is very good in this ETF. My favorite thing about the ETF is easily the diversification. If I’m going to be stuck with that expense ratio, I expect it to buy a fairly strong level of diversification and in this case it appears to do just that.

I have a strong preference for researching ETFs that are free to trade in my account, so most of my research will be on ETFs that fall under the “ETF OneSource” program. I like the correlation and the diversification in the holdings. Overall, the fund is looking pretty good. While I’m fairly cheap in regards to expense ratios, this one isn’t too bad. A few years ago I would have treated it as being very favorable, but I’m getting spoiled by seeing the ETFs with gross expense ratios under .10. I don’t place a large importance on historical returns (outside of risk), but the fund did underperform SPY by a fairly large amount over the holding period I used. The dividend adjusted close for SPY moved up by 49.11% and for IDLV it moved up 19.9%. I’m going to keep IDLV in my list of potential ETFs for international exposure, but if it makes the final round of challengers I’ll need to dig into the securities and make sure they are capable of producing higher levels of returns. Since it is an international equity fund, I’d be looking at a 5% to 10% allocation if it is selected.
