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.'

• Looking at the total return, or increase in value of -4.5% 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 (108.3%)
• During the last 3 years, the total return is 4.6%, which is lower, thus worse than the value of 49.1% from the benchmark.

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 performance (CAGR) over 5 years of iShares Core U.S. Aggregate Bond ETF is -0.9%, which is lower, thus worse compared to the benchmark SPY (15.8%) in the same period.
• Looking at compounded annual growth rate (CAGR) in of 1.5% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (14.3%).

Volatility:

'Volatility is a statistical measure of the dispersion of returns for a given security or market index. Volatility can either be measured by using the standard deviation or variance between returns from that same security or market index. Commonly, the higher the volatility, the riskier the security. In the securities markets, volatility is often associated with big swings in either direction. For example, when the stock market rises and falls more than one percent over a sustained period of time, it is called a 'volatile' market.'

• Compared with the benchmark SPY (17.9%) in the period of the last 5 years, the historical 30 days volatility of 6% of iShares Core U.S. Aggregate Bond ETF is smaller, thus better.
• During the last 3 years, the 30 days standard deviation is 6.9%, which is smaller, thus better than the value of 18.1% 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 4.3%, which is lower, thus better compared to the benchmark SPY (12.4%) in the same period.
• During the last 3 years, the downside risk is 4.7%, which is smaller, thus better than the value of 12.2% from the benchmark.

Sharpe:

'The Sharpe ratio was developed by Nobel laureate William F. Sharpe, and is used to help investors understand the return of an investment compared to its risk. The ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk. Subtracting the risk-free rate from the mean return allows an investor to better isolate the profits associated with risk-taking activities. One intuition of this calculation is that a portfolio engaging in 'zero risk' investments, such as the purchase of U.S. Treasury bills (for which the expected return is the risk-free rate), has a Sharpe ratio of exactly zero. Generally, the greater the value of the Sharpe ratio, the more attractive the risk-adjusted return.'

• Looking at the risk / return profile (Sharpe) of -0.57 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 (0.75)
• Compared with SPY (0.65) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of -0.14 is smaller, thus worse.

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 -0.8 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 (1.07)
• Looking at ratio of annual return and downside deviation in of -0.21 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.97).

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.'

• Compared with the benchmark SPY (8.49 ) in the period of the last 5 years, the Ulcer Ratio of 9.46 of iShares Core U.S. Aggregate Bond ETF is larger, thus worse.
• During the last 3 years, the Ulcer Index is 3.8 , which is lower, thus better than the value of 5.55 from the benchmark.

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.'

• Compared with the benchmark SPY (-24.5 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.
• Compared with SPY (-18.8 days) in the period of the last 3 years, the maximum drop from peak to valley of -9.8 days is higher, thus better.

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.'

• Compared with the benchmark SPY (488 days) in the period of the last 5 years, the maximum days below previous high of 1211 days of iShares Core U.S. Aggregate Bond ETF is higher, thus worse.
• During the last 3 years, the maximum time in days below previous high water mark is 487 days, which is greater, thus worse than the value of 199 days from the benchmark.

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.'

• The average time in days below previous high water mark over 5 years of iShares Core U.S. Aggregate Bond ETF is 595 days, which is greater, thus worse compared to the benchmark SPY (119 days) in the same period.
• During the last 3 years, the average days under water is 185 days, which is higher, thus worse than the value of 46 days from the benchmark.
