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

TotalReturn:

'Total return is the amount of value an investor earns from a security over a specific period, typically one year, when all distributions are reinvested. Total return is expressed as a percentage of the amount invested. For example, a total return of 20% means the security increased by 20% of its original value due to a price increase, distribution of dividends (if a stock), coupons (if a bond) or capital gains (if a fund). Total return is a strong measure of an investment’s overall performance.'

• The total return over 5 years of iShares Core U.S. Aggregate Bond ETF is 3.7%, which is smaller, thus worse compared to the benchmark SPY (67.8%) in the same period.
• During the last 3 years, the total return, or increase in value is -11.2%, which is lower, thus worse than the value of 44.5% from the benchmark.

CAGR:

'The compound annual growth rate isn't a true return rate, but rather a representational figure. It is essentially a number that describes the rate at which an investment would have grown if it had grown the same rate every year and the profits were reinvested at the end of each year. In reality, this sort of performance is unlikely. However, CAGR can be used to smooth returns so that they may be more easily understood when compared to alternative investments.'

• Compared with the benchmark SPY (10.9%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of 0.7% of iShares Core U.S. Aggregate Bond ETF is lower, thus worse.
• Looking at annual return (CAGR) in of -3.9% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (13.1%).

Volatility:

'Volatility is a rate at which the price of a security increases or decreases for a given set of returns. Volatility is measured by calculating the standard deviation of the annualized returns over a given period of time. It shows the range to which the price of a security may increase or decrease. Volatility measures the risk of a security. It is used in option pricing formula to gauge the fluctuations in the returns of the underlying assets. Volatility indicates the pricing behavior of the security and helps estimate the fluctuations that may happen in a short period of time.'

• Looking at the volatility of 6.1% in the last 5 years of iShares Core U.S. Aggregate Bond ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (21.4%)
• During the last 3 years, the 30 days standard deviation is 5.9%, which is smaller, thus better than the value of 18.8% from the benchmark.

DownVol:

'Risk measures typically quantify the downside risk, whereas the standard deviation (an example of a deviation risk measure) measures both the upside and downside risk. Specifically, downside risk in our definition is the semi-deviation, that is the standard deviation of all negative returns.'

• The downside deviation over 5 years of iShares Core U.S. Aggregate Bond ETF is 4.5%, which is lower, thus better compared to the benchmark SPY (15.4%) in the same period.
• Compared with SPY (13.3%) in the period of the last 3 years, the downside volatility of 4.3% is lower, thus better.

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.'

• Compared with the benchmark SPY (0.39) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of -0.29 of iShares Core U.S. Aggregate Bond ETF is lower, thus worse.
• Looking at risk / return profile (Sharpe) in of -1.08 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.56).

Sortino:

'The Sortino ratio improves upon the Sharpe ratio by isolating downside volatility from total volatility by dividing excess return by the downside deviation. The Sortino ratio is a variation of the Sharpe ratio that differentiates harmful volatility from total overall volatility by using the asset's standard deviation of negative asset returns, called downside deviation. The Sortino ratio takes the asset's return and subtracts the risk-free rate, and then divides that amount by the asset's downside deviation. The ratio was named after Frank A. Sortino.'

• Looking at the downside risk / excess return profile of -0.39 in the last 5 years of iShares Core U.S. Aggregate Bond ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (0.55)
• Looking at ratio of annual return and downside deviation in of -1.5 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.79).

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.'

• Compared with the benchmark SPY (9.46 ) in the period of the last 5 years, the Ulcer Index of 6.59 of iShares Core U.S. Aggregate Bond ETF is smaller, thus better.
• Compared with SPY (10 ) in the period of the last 3 years, the Ulcer Ratio of 8.46 is smaller, thus better.

MaxDD:

'Maximum drawdown is defined as the peak-to-trough decline of an investment during a specific period. It is usually quoted as a percentage of the peak value. The maximum drawdown can be calculated based on absolute returns, in order to identify strategies that suffer less during market downturns, such as low-volatility strategies. However, the maximum drawdown can also be calculated based on returns relative to a benchmark index, for identifying strategies that show steady outperformance over time.'

• Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum DrawDown of -18.4 days of iShares Core U.S. Aggregate Bond ETF is greater, thus better.
• During the last 3 years, the maximum DrawDown is -18.4 days, which is larger, thus better than the value of -24.5 days from the benchmark.

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.'

• Looking at the maximum days below previous high of 709 days 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 (352 days)
• Compared with SPY (352 days) in the period of the last 3 years, the maximum days under water of 709 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.'

• Compared with the benchmark SPY (78 days) in the period of the last 5 years, the average days under water of 228 days of iShares Core U.S. Aggregate Bond ETF is greater, thus worse.
• During the last 3 years, the average days under water is 344 days, which is higher, thus worse than the value of 102 days from the benchmark.
