'Total return, when measuring performance, is the actual rate of return of an investment or a pool of investments over a given evaluation period. Total return includes interest, capital gains, dividends and distributions realized over a given period of time. Total return accounts for two categories of return: income including interest paid by fixed-income investments, distributions or dividends and capital appreciation, representing the change in the market price of an asset.'

Using this definition on our asset we see for example:- Looking at the total return of 47.8% in the last 5 years of SPDR S&P Global Natural Resources ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (91.7%)
- Compared with SPY (47.9%) in the period of the last 3 years, the total return, or increase in value of 2.2% is lower, 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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (13.9%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of 8.1% of SPDR S&P Global Natural Resources ETF is lower, thus worse.
- Looking at annual return (CAGR) in of 0.7% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (13.9%).

'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 SPDR S&P Global Natural Resources ETF is 24%, which is greater, thus worse compared to the benchmark SPY (19%) in the same period.
- Looking at 30 days standard deviation in of 27.2% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (22.8%).

'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.'

Using this definition on our asset we see for example:- The downside volatility over 5 years of SPDR S&P Global Natural Resources ETF is 17.7%, which is larger, thus worse compared to the benchmark SPY (13.8%) in the same period.
- Looking at downside deviation in of 20.4% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (16.7%).

'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.'

Using this definition on our asset we see for example:- Looking at the Sharpe Ratio of 0.23 in the last 5 years of SPDR S&P Global Natural Resources ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.6)
- During the last 3 years, the ratio of return and volatility (Sharpe) is -0.06, which is smaller, thus worse than the value of 0.5 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 downside risk / excess return profile over 5 years of SPDR S&P Global Natural Resources ETF is 0.32, which is lower, thus worse compared to the benchmark SPY (0.82) in the same period.
- During the last 3 years, the ratio of annual return and downside deviation is -0.09, which is smaller, thus worse than the value of 0.68 from the benchmark.

'Ulcer Index is a method for measuring investment risk that addresses the real concerns of investors, unlike the widely used standard deviation of return. UI is a measure of the depth and duration of drawdowns in prices from earlier highs. Using Ulcer Index instead of standard deviation can lead to very different conclusions about investment risk and risk-adjusted return, especially when evaluating strategies that seek to avoid major declines in portfolio value (market timing, dynamic asset allocation, hedge funds, etc.). The Ulcer Index was originally developed in 1987. Since then, it has been widely recognized and adopted by the investment community. According to Nelson Freeburg, editor of Formula Research, Ulcer Index is “perhaps the most fully realized statistical portrait of risk there is.'

Which means for our asset as example:- Looking at the Downside risk index of 13 in the last 5 years of SPDR S&P Global Natural Resources ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (5.82 )
- Compared with SPY (7.14 ) in the period of the last 3 years, the Ulcer Ratio of 16 is larger, thus worse.

'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:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum DrawDown of -48.6 days of SPDR S&P Global Natural Resources ETF is smaller, thus worse.
- Looking at maximum DrawDown in of -48.6 days in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (-33.7 days).

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (139 days) in the period of the last 5 years, the maximum days below previous high of 636 days of SPDR S&P Global Natural Resources ETF is larger, thus worse.
- During the last 3 years, the maximum days below previous high is 636 days, which is larger, thus worse than the value of 139 days from the benchmark.

'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 below previous high of 186 days in the last 5 years of SPDR S&P Global Natural Resources ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (36 days)
- During the last 3 years, the average days under water is 280 days, which is greater, thus worse than the value of 45 days from the benchmark.
