'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (65.8%) in the period of the last 5 years, the total return, or increase in value of 46.5% of Invesco BuyBack Achievers ETF is smaller, thus worse.
- Compared with SPY (48.8%) in the period of the last 3 years, the total return, or performance of 41.4% is lower, thus worse.

'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 annual return (CAGR) over 5 years of Invesco BuyBack Achievers ETF is 7.9%, which is lower, thus worse compared to the benchmark SPY (10.6%) in the same period.
- During the last 3 years, the compounded annual growth rate (CAGR) is 12.3%, which is smaller, thus worse than the value of 14.2% from the benchmark.

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (13.6%) in the period of the last 5 years, the volatility of 14.4% of Invesco BuyBack Achievers ETF is larger, thus worse.
- Looking at 30 days standard deviation in of 13.6% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (12.8%).

'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.'

Which means for our asset as example:- Looking at the downside risk of 15.8% in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (15%)
- Compared with SPY (14.6%) in the period of the last 3 years, the downside volatility of 15.3% is higher, thus worse.

'The Sharpe ratio (also known as the Sharpe index, the Sharpe measure, and the reward-to-variability ratio) is a way to examine the performance of an investment by adjusting for its risk. The ratio measures the excess return (or risk premium) per unit of deviation in an investment asset or a trading strategy, typically referred to as risk, named after William F. Sharpe.'

Which means for our asset as example:- The Sharpe Ratio over 5 years of Invesco BuyBack Achievers ETF is 0.38, which is lower, thus worse compared to the benchmark SPY (0.6) in the same period.
- Looking at ratio of return and volatility (Sharpe) in of 0.72 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.91).

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (0.54) in the period of the last 5 years, the ratio of annual return and downside deviation of 0.34 of Invesco BuyBack Achievers ETF is lower, thus worse.
- Compared with SPY (0.8) in the period of the last 3 years, the downside risk / excess return profile of 0.64 is lower, thus worse.

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (4.03 ) in the period of the last 5 years, the Downside risk index of 6.15 of Invesco BuyBack Achievers ETF is higher, thus worse.
- Compared with SPY (4.1 ) in the period of the last 3 years, the Downside risk index of 5.45 is larger, thus worse.

'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:- Compared with the benchmark SPY (-19.3 days) in the period of the last 5 years, the maximum DrawDown of -21.2 days of Invesco BuyBack Achievers ETF is smaller, thus worse.
- Looking at maximum reduction from previous high in of -21.2 days in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (-19.3 days).

'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) in days.'

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 435 days of Invesco BuyBack Achievers ETF is higher, thus worse.
- During the last 3 years, the maximum time in days below previous high water mark is 305 days, which is greater, thus worse than the value of 139 days from the benchmark.

'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:- The average days under water over 5 years of Invesco BuyBack Achievers ETF is 129 days, which is larger, thus worse compared to the benchmark SPY (41 days) in the same period.
- During the last 3 years, the average days under water is 79 days, which is higher, thus worse than the value of 35 days from the benchmark.
