iShares Core U.S. Aggregate Bond ETF (AGG)

TotalReturn:

'Total return, when measuring performance, is the actual rate of return of an investment or a pool of investments over a given evaluation period. Total return includes interest, capital gains, dividends and distributions realized over a given period of time. Total return accounts for two categories of return: income including interest paid by fixed-income investments, distributions or dividends and capital appreciation, representing the change in the market price of an asset.'

• The total return, or increase in value over 5 years of iShares Core U.S. Aggregate Bond ETF is -4.7%, which is lower, thus worse compared to the benchmark SPY (113.2%) in the same period.
• Compared with SPY (67.5%) in the period of the last 3 years, the total return, or performance of 7.7% is lower, thus worse.

CAGR:

'The compound annual growth rate (CAGR) is a useful measure of growth over multiple time periods. It can be thought of as the growth rate that gets you from the initial investment value to the ending investment value if you assume that the investment has been compounding over the time period.'

• The annual return (CAGR) over 5 years of iShares Core U.S. Aggregate Bond ETF is -1%, which is smaller, thus worse compared to the benchmark SPY (16.4%) in the same period.
• Compared with SPY (18.9%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of 2.5% is lower, thus worse.

Volatility:

'In finance, volatility (symbol σ) is the degree of variation of a trading price series over time as measured by the standard deviation of logarithmic returns. Historic volatility measures a time series of past market prices. Implied volatility looks forward in time, being derived from the market price of a market-traded derivative (in particular, an option). Commonly, the higher the volatility, the riskier the security.'

• Compared with the benchmark SPY (17.5%) in the period of the last 5 years, the 30 days standard deviation of 6% of iShares Core U.S. Aggregate Bond ETF is lower, thus better.
• Looking at historical 30 days volatility in of 6.7% in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (17.5%).

DownVol:

'The downside volatility is similar to the volatility, or standard deviation, but only takes losing/negative periods into account.'

• The downside volatility over 5 years of iShares Core U.S. Aggregate Bond ETF is 4.3%, which is lower, thus better compared to the benchmark SPY (12.1%) in the same period.
• Looking at downside volatility in of 4.6% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (11.6%).

Sharpe:

'The Sharpe ratio (also known as the Sharpe index, the Sharpe measure, and the reward-to-variability ratio) is a way to examine the performance of an investment by adjusting for its risk. The ratio measures the excess return (or risk premium) per unit of deviation in an investment asset or a trading strategy, typically referred to as risk, named after William F. Sharpe.'

• Looking at the ratio of return and volatility (Sharpe) of -0.57 in the last 5 years of iShares Core U.S. Aggregate Bond ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.79)
• Compared with SPY (0.94) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of 0 is lower, thus worse.

Sortino:

'The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally. Though both ratios measure an investment's risk-adjusted return, they do so in significantly different ways that will frequently lead to differing conclusions as to the true nature of the investment's return-generating efficiency. The Sortino ratio is used as a way to compare the risk-adjusted performance of programs with differing risk and return profiles. In general, risk-adjusted returns seek to normalize the risk across programs and then see which has the higher return unit per risk.'

• The ratio of annual return and downside deviation over 5 years of iShares Core U.S. Aggregate Bond ETF is -0.81, which is lower, thus worse compared to the benchmark SPY (1.15) in the same period.
• During the last 3 years, the downside risk / excess return profile is 0, which is lower, thus worse than the value of 1.42 from the benchmark.

Ulcer:

'Ulcer Index is a method for measuring investment risk that addresses the real concerns of investors, unlike the widely used standard deviation of return. UI is a measure of the depth and duration of drawdowns in prices from earlier highs. Using Ulcer Index instead of standard deviation can lead to very different conclusions about investment risk and risk-adjusted return, especially when evaluating strategies that seek to avoid major declines in portfolio value (market timing, dynamic asset allocation, hedge funds, etc.). The Ulcer Index was originally developed in 1987. Since then, it has been widely recognized and adopted by the investment community. According to Nelson Freeburg, editor of Formula Research, Ulcer Index is “perhaps the most fully realized statistical portrait of risk there is.'

• Looking at the Downside risk index of 9.51 in the last 5 years of iShares Core U.S. Aggregate Bond ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (8.48 )
• Compared with SPY (5.31 ) in the period of the last 3 years, the Downside risk index of 3.79 is smaller, thus better.

MaxDD:

'A maximum drawdown is the maximum loss from a peak to a trough of a portfolio, before a new peak is attained. Maximum Drawdown is an indicator of downside risk over a specified time period. It can be used both as a stand-alone measure or as an input into other metrics such as 'Return over Maximum Drawdown' and the Calmar Ratio. Maximum Drawdown is expressed in percentage terms.'

• Compared with the benchmark SPY (-24.5 days) in the period of the last 5 years, the maximum reduction from previous high of -18.4 days of iShares Core U.S. Aggregate Bond ETF is greater, thus better.
• Compared with SPY (-18.8 days) in the period of the last 3 years, the maximum reduction from previous high of -9.8 days is larger, thus better.

MaxDuration:

'The Drawdown Duration is the length of any peak to peak period, or the time between new equity highs. The Max Drawdown Duration is the worst (the maximum/longest) amount of time an investment has seen between peaks (equity highs) in days.'

• The maximum days below previous high over 5 years of iShares Core U.S. Aggregate Bond ETF is 1237 days, which is larger, thus worse compared to the benchmark SPY (488 days) in the same period.
• Compared with SPY (199 days) in the period of the last 3 years, the maximum days below previous high of 487 days is higher, thus worse.

AveDuration:

'The Drawdown Duration is the length of any peak to peak period, or the time between new equity highs. The Avg Drawdown Duration is the average amount of time an investment has seen between peaks (equity highs), or in other terms the average of time under water of all drawdowns. So in contrast to the Maximum duration it does not measure only one drawdown event but calculates the average of all.'

• The average days under water over 5 years of iShares Core U.S. Aggregate Bond ETF is 617 days, which is higher, thus worse compared to the benchmark SPY (120 days) in the same period.
• During the last 3 years, the average days below previous high is 191 days, which is larger, thus worse than the value of 47 days from the benchmark.
