'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 54.1% in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (61.9%)
- Looking at total return in of 97.7% in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (79.4%).

'Compound annual growth rate (CAGR) is a business and investing specific term for the geometric progression ratio that provides a constant rate of return over the time period. CAGR is not an accounting term, but it is often used to describe some element of the business, for example revenue, units delivered, registered users, etc. CAGR dampens the effect of volatility of periodic returns that can render arithmetic means irrelevant. It is particularly useful to compare growth rates from various data sets of common domain such as revenue growth of companies in the same industry.'

Using this definition on our asset we see for example:- The compounded annual growth rate (CAGR) over 5 years of Invesco BuyBack Achievers ETF is 9%, which is smaller, thus worse compared to the benchmark SPY (10.1%) in the same period.
- Compared with SPY (21.5%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of 25.5% is greater, thus better.

'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.'

Which means for our asset as example:- Looking at the 30 days standard deviation of 24.1% in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (21.5%)
- Looking at historical 30 days volatility in of 23.8% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (21.2%).

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (15.5%) in the period of the last 5 years, the downside risk of 17.2% of Invesco BuyBack Achievers ETF is larger, thus worse.
- Looking at downside risk in of 15.5% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (14.1%).

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (0.36) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of 0.27 of Invesco BuyBack Achievers ETF is smaller, thus worse.
- During the last 3 years, the risk / return profile (Sharpe) is 0.97, which is higher, thus better than the value of 0.9 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.'

Applying this definition to our asset in some examples:- Looking at the downside risk / excess return profile of 0.38 in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.49)
- Compared with SPY (1.35) in the period of the last 3 years, the downside risk / excess return profile of 1.49 is higher, thus better.

'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:- Compared with the benchmark SPY (9.15 ) in the period of the last 5 years, the Ulcer Ratio of 10 of Invesco BuyBack Achievers ETF is greater, thus worse.
- Compared with SPY (9.78 ) in the period of the last 3 years, the Ulcer Index of 8.49 is lower, thus better.

'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.'

Which means for our asset as example:- Looking at the maximum reduction from previous high of -40.9 days in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (-33.7 days)
- Compared with SPY (-24.5 days) in the period of the last 3 years, the maximum drop from peak to valley of -23.5 days is higher, thus better.

'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:- Looking at the maximum days below previous high of 344 days in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (305 days)
- Looking at maximum days under water in of 344 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (305 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.'

Using this definition on our asset we see for example:- The average days below previous high over 5 years of Invesco BuyBack Achievers ETF is 87 days, which is larger, thus worse compared to the benchmark SPY (65 days) in the same period.
- During the last 3 years, the average days under water is 94 days, which is greater, thus worse than the value of 80 days from the benchmark.
