'Total return is the amount of value an investor earns from a security over a specific period, typically one year, when all distributions are reinvested. Total return is expressed as a percentage of the amount invested. For example, a total return of 20% means the security increased by 20% of its original value due to a price increase, distribution of dividends (if a stock), coupons (if a bond) or capital gains (if a fund). Total return is a strong measure of an investment’s overall performance.'

Using this definition on our asset we see for example:- The total return, or increase in value over 5 years of Invesco BuyBack Achievers ETF is 45.7%, which is lower, thus worse compared to the benchmark SPY (67.3%) in the same period.
- Compared with SPY (46.1%) in the period of the last 3 years, the total return, or increase in value of 35.3% is smaller, thus worse.

'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.'

Which means for our asset as example:- The annual performance (CAGR) over 5 years of Invesco BuyBack Achievers ETF is 7.8%, which is smaller, thus worse compared to the benchmark SPY (10.9%) in the same period.
- During the last 3 years, the annual return (CAGR) is 10.6%, which is lower, thus worse than the value of 13.5% 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.'

Which means for our asset as example:- Compared with the benchmark SPY (13.2%) in the period of the last 5 years, the historical 30 days volatility of 13.9% of Invesco BuyBack Achievers ETF is higher, thus worse.
- During the last 3 years, the historical 30 days volatility is 13.1%, which is larger, thus worse than the value of 12.4% from the benchmark.

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

Using this definition on our asset we see for example:- Compared with the benchmark SPY (14.6%) in the period of the last 5 years, the downside deviation of 15.2% of Invesco BuyBack Achievers ETF is larger, thus worse.
- During the last 3 years, the downside deviation is 14.6%, which is larger, thus worse than the value of 14% from the benchmark.

'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:- Compared with the benchmark SPY (0.63) in the period of the last 5 years, the risk / return profile (Sharpe) of 0.38 of Invesco BuyBack Achievers ETF is lower, thus worse.
- Compared with SPY (0.88) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of 0.62 is smaller, thus worse.

'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.'

Using this definition on our asset we see for example:- Looking at the ratio of annual return and downside deviation of 0.35 in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.57)
- Looking at downside risk / excess return profile in of 0.56 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 BuyBack Achievers ETF is 6.05 , which is higher, thus better compared to the benchmark SPY (3.95 ) in the same period.
- Compared with SPY (4 ) in the period of the last 3 years, the Ulcer Index of 5.28 is larger, 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 -21.2 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 (-19.3 days)
- During the last 3 years, the maximum drop from peak to valley is -21.2 days, which is lower, thus worse than the value of -19.3 days from the benchmark.

'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'

Applying this definition to our asset in some examples:- Looking at the maximum days under water of 435 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 (187 days)
- Looking at maximum days below previous high in of 287 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (131 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.'

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 124 days, which is higher, thus worse compared to the benchmark SPY (39 days) in the same period.
- Compared with SPY (33 days) in the period of the last 3 years, the average days below previous high of 72 days is greater, thus worse.
