But the trade-off is a greater cost and a lower one-year return. </p><p>MUB is a good ETF for high-income investors, but it would not be an ETF to add to a retirement account, such as an IRA, if you want to take advantage of the tax benefits. IEI is for those who prioritize safety and low volatility although the income is subject to federal income tax.</p><h2>Should you buy stock in iShares Trust - iShares 3-7 Year Treasury Bond ETF right now?</h2>
