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

TotalReturn:

'The total return on a portfolio of investments takes into account not only the capital appreciation on the portfolio, but also the income received on the portfolio. The income typically consists of interest, dividends, and securities lending fees. This contrasts with the price return, which takes into account only the capital gain on an investment.'

• The total return over 5 years of iShares Core U.S. Aggregate Bond ETF is -1.8%, which is smaller, thus worse compared to the benchmark SPY (80.7%) in the same period.
• Looking at total return, or performance in of 13.1% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (76%).

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.'

• The compounded annual growth rate (CAGR) over 5 years of iShares Core U.S. Aggregate Bond ETF is -0.4%, which is lower, thus worse compared to the benchmark SPY (12.6%) in the same period.
• Compared with SPY (20.9%) in the period of the last 3 years, the annual return (CAGR) of 4.2% is lower, thus worse.

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 30 days standard deviation 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 (17.2%)
• Looking at volatility in of 5.2% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (15.3%).

DownVol:

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

• Looking at the downside volatility of 4.3% 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 (11.9%)
• During the last 3 years, the downside volatility is 3.6%, which is lower, thus better than the value of 10.3% from the benchmark.

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.'

• The ratio of return and volatility (Sharpe) over 5 years of iShares Core U.S. Aggregate Bond ETF is -0.47, which is smaller, thus worse compared to the benchmark SPY (0.59) in the same period.
• Looking at Sharpe Ratio in of 0.32 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (1.2).

Sortino:

'The Sortino ratio, a variation of the Sharpe ratio only factors in the downside, or negative volatility, rather than the total volatility used in calculating the Sharpe ratio. The theory behind the Sortino variation is that upside volatility is a plus for the investment, and it, therefore, should not be included in the risk calculation. Therefore, the Sortino ratio takes upside volatility out of the equation and uses only the downside standard deviation in its calculation instead of the total standard deviation that is used in calculating the Sharpe ratio.'

• Looking at the excess return divided by the downside deviation of -0.66 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 (0.85)
• Looking at ratio of annual return and downside deviation in of 0.47 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (1.79).

Ulcer:

'The ulcer index is a stock market risk measure or technical analysis indicator devised by Peter Martin in 1987, and published by him and Byron McCann in their 1989 book The Investors Guide to Fidelity Funds. It's designed as a measure of volatility, but only volatility in the downward direction, i.e. the amount of drawdown or retracement occurring over a period. Other volatility measures like standard deviation treat up and down movement equally, but a trader doesn't mind upward movement, it's the downside that causes stress and stomach ulcers that the index's name suggests.'

• Looking at the Downside risk index of 8.91 in the last 5 years of iShares Core U.S. Aggregate Bond ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (8.46 )
• Looking at Ulcer Ratio in of 1.76 in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (3.37 ).

MaxDD:

'Maximum drawdown measures the loss in any losing period during a fund’s investment record. It is defined as the percent retrenchment from a fund’s peak value to the fund’s valley value. The drawdown is in effect from the time the fund’s retrenchment begins until a new fund high is reached. The maximum drawdown encompasses both the period from the fund’s peak to the fund’s valley (length), and the time from the fund’s valley to a new fund high (recovery). It measures the largest percentage drawdown that has occurred in any fund’s data record.'

• The maximum drop from peak to valley over 5 years of iShares Core U.S. Aggregate Bond ETF is -17.7 days, which is larger, thus better compared to the benchmark SPY (-24.5 days) in the same period.
• During the last 3 years, the maximum reduction from previous high is -4.8 days, which is larger, thus better than the value of -18.8 days from the benchmark.

MaxDuration:

'The Maximum Drawdown Duration is an extension of the Maximum Drawdown. However, this metric does not explain the drawdown in dollars or percentages, rather in days, weeks, or months. It is the length of time the account was in the Max Drawdown. A Max Drawdown measures a retrenchment from when an equity curve reaches a new high. It’s the maximum an account lost during that retrenchment. This method is applied because a valley can’t be measured until a new high occurs. Once the new high is reached, the percentage change from the old high to the bottom of the largest trough is recorded.'

• Looking at the maximum time in days below previous high water mark of 1116 days in the last 5 years of iShares Core U.S. Aggregate Bond ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (488 days)
• Looking at maximum days below previous high in of 195 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (87 days).

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 below previous high over 5 years of iShares Core U.S. Aggregate Bond ETF is 505 days, which is greater, thus worse compared to the benchmark SPY (118 days) in the same period.
• Compared with SPY (18 days) in the period of the last 3 years, the average days under water of 54 days is larger, thus worse.
