'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.'

Applying this definition to our asset in some examples:- Looking at the total return of 30.3% in the last 5 years of Invesco Emerging Markets Sovereign Debt ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (67.3%)
- During the last 3 years, the total return, or performance is 14.6%, which is lower, thus worse than the value of 46.1% from the benchmark.

'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.'

Which means for our asset as example:- The annual performance (CAGR) over 5 years of Invesco Emerging Markets Sovereign Debt ETF is 5.4%, which is smaller, thus worse compared to the benchmark SPY (10.9%) in the same period.
- Looking at annual performance (CAGR) in of 4.7% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (13.5%).

'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.'

Applying this definition to our asset in some examples:- Looking at the 30 days standard deviation of 6.5% in the last 5 years of Invesco Emerging Markets Sovereign Debt ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (13.2%)
- Looking at 30 days standard deviation in of 6.3% in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (12.4%).

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (14.6%) in the period of the last 5 years, the downside deviation of 7% of Invesco Emerging Markets Sovereign Debt ETF is lower, thus better.
- Looking at downside risk in of 7.1% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (14%).

'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.'

Applying this definition to our asset in some examples:- The Sharpe Ratio over 5 years of Invesco Emerging Markets Sovereign Debt ETF is 0.45, which is lower, thus worse compared to the benchmark SPY (0.63) in the same period.
- Compared with SPY (0.88) in the period of the last 3 years, the Sharpe Ratio of 0.34 is smaller, thus worse.

'The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally. Though both ratios measure an investment's risk-adjusted return, they do so in significantly different ways that will frequently lead to differing conclusions as to the true nature of the investment's return-generating efficiency. The Sortino ratio is used as a way to compare the risk-adjusted performance of programs with differing risk and return profiles. In general, risk-adjusted returns seek to normalize the risk across programs and then see which has the higher return unit per risk.'

Which means for our asset as example:- Looking at the ratio of annual return and downside deviation of 0.42 in the last 5 years of Invesco Emerging Markets Sovereign Debt ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.57)
- Looking at ratio of annual return and downside deviation in of 0.3 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.79).

'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.'

Which means for our asset as example:- The Downside risk index over 5 years of Invesco Emerging Markets Sovereign Debt ETF is 3.79 , which is lower, thus worse compared to the benchmark SPY (3.95 ) in the same period.
- Looking at Downside risk index in of 4.57 in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (4 ).

'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.'

Using this definition on our asset we see for example:- The maximum drop from peak to valley over 5 years of Invesco Emerging Markets Sovereign Debt ETF is -10.2 days, which is larger, thus better compared to the benchmark SPY (-19.3 days) in the same period.
- Compared with SPY (-19.3 days) in the period of the last 3 years, the maximum reduction from previous high of -10.2 days is higher, thus better.

'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'

Which means for our asset as example:- The maximum days below previous high over 5 years of Invesco Emerging Markets Sovereign Debt ETF is 300 days, which is larger, thus worse compared to the benchmark SPY (187 days) in the same period.
- Looking at maximum days under water in of 300 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (131 days).

'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.'

Applying this definition to our asset in some examples:- Looking at the average time in days below previous high water mark of 74 days in the last 5 years of Invesco Emerging Markets Sovereign Debt ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (39 days)
- During the last 3 years, the average days below previous high is 95 days, which is higher, thus worse than the value of 33 days from the benchmark.
