'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:- Compared with the benchmark SPY (80%) in the period of the last 5 years, the total return, or increase in value of -11.5% of Global X Fertilizers/Potash ETF is lower, thus worse.
- Looking at total return in of -10.5% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (31.8%).

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (12.5%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of -2.5% of Global X Fertilizers/Potash ETF is smaller, thus worse.
- During the last 3 years, the compounded annual growth rate (CAGR) is -3.7%, which is lower, thus worse than the value of 9.7% 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:- Looking at the historical 30 days volatility of 22.4% in the last 5 years of Global X Fertilizers/Potash ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (21.3%)
- During the last 3 years, the volatility is 24.4%, which is greater, thus worse than the value of 17.6% from the benchmark.

'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.'

Applying this definition to our asset in some examples:- The downside volatility over 5 years of Global X Fertilizers/Potash ETF is 16.6%, which is greater, thus worse compared to the benchmark SPY (15.3%) in the same period.
- During the last 3 years, the downside risk is 18.3%, which is larger, thus worse than the value of 12.3% from the benchmark.

'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:- The risk / return profile (Sharpe) over 5 years of Global X Fertilizers/Potash ETF is -0.22, which is lower, thus worse compared to the benchmark SPY (0.47) in the same period.
- During the last 3 years, the Sharpe Ratio is -0.25, which is lower, thus worse than the value of 0.41 from the benchmark.

'The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally. Though both ratios measure an investment's risk-adjusted return, they do so in significantly different ways that will frequently lead to differing conclusions as to the true nature of the investment's return-generating efficiency. The Sortino ratio is used as a way to compare the risk-adjusted performance of programs with differing risk and return profiles. In general, risk-adjusted returns seek to normalize the risk across programs and then see which has the higher return unit per risk.'

Using this definition on our asset we see for example:- Looking at the downside risk / excess return profile of -0.3 in the last 5 years of Global X Fertilizers/Potash ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (0.66)
- During the last 3 years, the ratio of annual return and downside deviation is -0.34, which is smaller, thus worse than the value of 0.58 from the benchmark.

'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 (9.43 ) in the period of the last 5 years, the Ulcer Index of 16 of Global X Fertilizers/Potash ETF is larger, thus worse.
- Compared with SPY (10 ) in the period of the last 3 years, the Ulcer Index of 18 is greater, thus worse.

'A maximum drawdown is the maximum loss from a peak to a trough of a portfolio, before a new peak is attained. Maximum Drawdown is an indicator of downside risk over a specified time period. It can be used both as a stand-alone measure or as an input into other metrics such as 'Return over Maximum Drawdown' and the Calmar Ratio. Maximum Drawdown is expressed in percentage terms.'

Applying this definition to our asset in some examples:- The maximum DrawDown over 5 years of Global X Fertilizers/Potash ETF is -50.3 days, which is smaller, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
- Looking at maximum reduction from previous high in of -50.3 days in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (-24.5 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:- Looking at the maximum days below previous high of 642 days in the last 5 years of Global X Fertilizers/Potash ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (480 days)
- Looking at maximum time in days below previous high water mark in of 642 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (480 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:- Compared with the benchmark SPY (119 days) in the period of the last 5 years, the average days under water of 267 days of Global X Fertilizers/Potash ETF is greater, thus worse.
- Compared with SPY (174 days) in the period of the last 3 years, the average days below previous high of 287 days is greater, thus worse.
