When buying normal bonds, the buyer needs to take note of accrued interest. He should take note whether the price quoted is a clean (excludes accrued interest) or dirty price (includes accrued interest). How about buyers of bond ETFs? Do they need to take note of the accrued interest before buying? I tried googling and am still confused at this point.
No. Investors purchase ETFs' as they would any other stock, own it under the same circumstances as an equity investment, collecting distributions instead of dividends or interest. The ETF takes care of the internal operations (bond maturities and turnover, accrued interest, payment dates, etc.).
