| The iShares Core U.S. Aggregate Bond ETF (the “Fund”) seeks to track the investment results of an index composed of the total U.S. investment-grade bond market, as represented by the Barclays U.S. Aggregate Bond Index (the “Index”). The Fund invests in a representative sample of securities included in the Index that collectively has an investment profile similar to the Index. Due to the use of representative sampling, the Fund may or may not hold all of the securities that are included in the Index. As of Feb 28 2015, the Fund's total assets were $34,333,901,537and the Fund's investment portfolio was valued at $34,051,766,237. The AGG YTD return is shown above.
The YTD Return on the AGG YTD return page and across the coverage universe of our site,
is a measure of the total return for a given investment year-to-date for the current calendar year
(up to the end of prior trading session). Arguably, choosing the current calendar year for a measurement
period is on the one hand completely arbitrary, but on the other hand a year-to-date look can be extremely
useful in the context of our country's tax system which taxes gains and income on a calendar year basis.
Thus, researching Year-To-Date Returns is good practice for investors — whether AGG YTD return or other benchmarks/peers
— and when doing so it is also important to factor in dividends, because a financial instrument's YTD return is
more than just the change in price if that instrument pays a dividend or coupon. Our website aims to empower investors
by performing the AGG YTD return calculation (with any dividends reinvested as applicable), and to provide a
coverage universe of many stocks and ETFs to be able to compare YTD returns.
