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.'

• Compared with the benchmark SPY (109.7%) in the period of the last 5 years, the total return, or performance of -5.4% of iShares Core U.S. Aggregate Bond ETF is lower, thus worse.
• Compared with SPY (70.1%) in the period of the last 3 years, the total return of 6% is lower, thus worse.

CAGR:

'Compound annual growth rate (CAGR) is a business and investing specific term for the geometric progression ratio that provides a constant rate of return over the time period. CAGR is not an accounting term, but it is often used to describe some element of the business, for example revenue, units delivered, registered users, etc. CAGR dampens the effect of volatility of periodic returns that can render arithmetic means irrelevant. It is particularly useful to compare growth rates from various data sets of common domain such as revenue growth of companies in the same industry.'

• Looking at the annual return (CAGR) of -1.1% 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 (16%)
• Looking at annual return (CAGR) in of 2% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (19.5%).

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% 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 (17.5%)
• Looking at 30 days standard deviation in of 6.7% in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (17.4%).

DownVol:

'Downside risk is the financial risk associated with losses. That is, it is the risk of the actual return being below the expected return, or the uncertainty about the magnitude of that difference. 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.'

• 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 smaller, thus better in comparison to the benchmark SPY (12.1%)
• Compared with SPY (11.5%) in the period of the last 3 years, the downside deviation of 4.6% is lower, thus better.

Sharpe:

'The Sharpe ratio is the measure of risk-adjusted return of a financial portfolio. Sharpe ratio is a measure of excess portfolio return over the risk-free rate relative to its standard deviation. Normally, the 90-day Treasury bill rate is taken as the proxy for risk-free rate. A portfolio with a higher Sharpe ratio is considered superior relative to its peers. The measure was named after William F Sharpe, a Nobel laureate and professor of finance, emeritus at Stanford University.'

• Compared with the benchmark SPY (0.77) in the period of the last 5 years, the risk / return profile (Sharpe) of -0.6 of iShares Core U.S. Aggregate Bond ETF is lower, thus worse.
• Compared with SPY (0.97) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of -0.08 is lower, thus worse.

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.'

• The ratio of annual return and downside deviation over 5 years of iShares Core U.S. Aggregate Bond ETF is -0.84, which is smaller, thus worse compared to the benchmark SPY (1.12) in the same period.
• During the last 3 years, the downside risk / excess return profile is -0.12, which is smaller, thus worse than the value of 1.47 from the benchmark.

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 Ulcer Ratio of 9.52 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 )
• Looking at Downside risk index in of 3.78 in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (5.3 ).

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.'

• The maximum drop from peak to valley over 5 years of iShares Core U.S. Aggregate Bond ETF is -18.4 days, which is higher, thus better compared to the benchmark SPY (-24.5 days) in the same period.
• Compared with SPY (-18.8 days) in the period of the last 3 years, the maximum DrawDown of -9.8 days is higher, 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). Many assume Max DD Duration is the length of time between new highs during which the Max DD (magnitude) occurred. But that isn’t always the case. The Max DD duration is the longest time between peaks, period. So it could be the time when the program also had its biggest peak to valley loss (and usually is, because the program needs a long time to recover from the largest loss), but it doesn’t have to be'

• Looking at the maximum days under water of 1243 days in the last 5 years of iShares Core U.S. Aggregate Bond ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (488 days)
• Compared with SPY (199 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 487 days is greater, thus worse.

AveDuration:

'The Average 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. 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.'

• Looking at the average days under water of 621 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 (120 days)
• During the last 3 years, the average days under water is 190 days, which is larger, thus worse than the value of 47 days from the benchmark.
