'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.'

Which means for our asset as example:- Looking at the total return of 10.4% in the last 5 years of Invesco Ultra Short Duration ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (74.4%)
- During the last 3 years, the total return, or performance is 7.4%, which is lower, thus worse than the value of 47.2% 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.'

Applying this definition to our asset in some examples:- The compounded annual growth rate (CAGR) over 5 years of Invesco Ultra Short Duration ETF is 2%, which is lower, thus worse compared to the benchmark SPY (11.8%) in the same period.
- Looking at annual return (CAGR) in of 2.4% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (13.8%).

'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.'

Which means for our asset as example:- The 30 days standard deviation over 5 years of Invesco Ultra Short Duration ETF is 0.5%, which is lower, thus better compared to the benchmark SPY (13.6%) in the same period.
- Looking at historical 30 days volatility in of 0.4% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (12.9%).

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

Applying this definition to our asset in some examples:- The downside volatility over 5 years of Invesco Ultra Short Duration ETF is 0.7%, which is lower, thus better compared to the benchmark SPY (14.9%) in the same period.
- Looking at downside deviation in of 0.6% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (14.6%).

'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.'

Which means for our asset as example:- Looking at the Sharpe Ratio of -0.95 in the last 5 years of Invesco Ultra Short Duration ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.68)
- During the last 3 years, the risk / return profile (Sharpe) is -0.17, which is smaller, thus worse than the value of 0.88 from the benchmark.

'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.'

Which means for our asset as example:- The excess return divided by the downside deviation over 5 years of Invesco Ultra Short Duration ETF is -0.69, which is lower, thus worse compared to the benchmark SPY (0.62) in the same period.
- Looking at downside risk / excess return profile in of -0.11 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.77).

'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.'

Which means for our asset as example:- Looking at the Ulcer Index of 0.05 in the last 5 years of Invesco Ultra Short Duration ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (3.99 )
- During the last 3 years, the Downside risk index is 0.03 , which is lower, thus better than the value of 4.1 from the benchmark.

'Maximum drawdown is defined as the peak-to-trough decline of an investment during a specific period. It is usually quoted as a percentage of the peak value. The maximum drawdown can be calculated based on absolute returns, in order to identify strategies that suffer less during market downturns, such as low-volatility strategies. However, the maximum drawdown can also be calculated based on returns relative to a benchmark index, for identifying strategies that show steady outperformance over time.'

Applying this definition to our asset in some examples:- The maximum drop from peak to valley over 5 years of Invesco Ultra Short Duration ETF is -0.4 days, which is larger, thus better compared to the benchmark SPY (-19.3 days) in the same period.
- During the last 3 years, the maximum DrawDown is -0.3 days, which is higher, thus better than the value of -19.3 days from the benchmark.

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (187 days) in the period of the last 5 years, the maximum days below previous high of 47 days of Invesco Ultra Short Duration ETF is lower, thus better.
- Looking at maximum time in days below previous high water mark in of 15 days in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (139 days).

'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.'

Applying this definition to our asset in some examples:- Looking at the average days under water of 6 days in the last 5 years of Invesco Ultra Short Duration ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (41 days)
- Looking at average time in days below previous high water mark in of 3 days in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (36 days).
