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, or performance over 5 years of iShares Core U.S. Aggregate Bond ETF is 4.9%, which is smaller, thus worse compared to the benchmark SPY (63%) in the same period.
• During the last 3 years, the total return, or performance is -7.1%, which is smaller, thus worse than the value of 33.5% 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.'

• Looking at the annual performance (CAGR) of 1% 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 (10.3%)
• Compared with SPY (10.1%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of -2.4% 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.'

• Looking at the 30 days standard deviation of 5.8% 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 (21.6%)
• Compared with SPY (25.1%) in the period of the last 3 years, the historical 30 days volatility of 7.1% is lower, thus better.

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.'

• Looking at the downside risk of 4.4% 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 (15.6%)
• Looking at downside volatility in of 5.4% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (18.1%).

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.'

• The ratio of return and volatility (Sharpe) over 5 years of iShares Core U.S. Aggregate Bond ETF is -0.26, which is lower, thus worse compared to the benchmark SPY (0.36) in the same period.
• Looking at risk / return profile (Sharpe) in of -0.69 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.3).

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 excess return divided by the downside deviation over 5 years of iShares Core U.S. Aggregate Bond ETF is -0.35, which is smaller, thus worse compared to the benchmark SPY (0.5) in the same period.
• Compared with SPY (0.42) in the period of the last 3 years, the excess return divided by the downside deviation of -0.91 is lower, thus worse.

Ulcer:

'The Ulcer Index is a technical indicator that measures downside risk, in terms of both the depth and duration of price declines. The index increases in value as the price moves farther away from a recent high and falls as the price rises to new highs. The indicator is usually calculated over a 14-day period, with the Ulcer Index showing the percentage drawdown a trader can expect from the high over that period. The greater the value of the Ulcer Index, the longer it takes for a stock to get back to the former high.'

• Compared with the benchmark SPY (8.88 ) in the period of the last 5 years, the Downside risk index of 5.72 of iShares Core U.S. Aggregate Bond ETF is lower, thus better.
• Looking at Ulcer Index in of 7.36 in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (11 ).

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 DrawDown 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 (-33.7 days) in the same period.
• During the last 3 years, the maximum drop from peak to valley is -18.4 days, which is higher, thus better than the value of -33.7 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 days under water of 630 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 (273 days)
• Compared with SPY (273 days) in the period of the last 3 years, the maximum days below previous high of 630 days is larger, 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 below previous high of 186 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 (57 days)
• Looking at average days below previous high in of 277 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (73 days).
