'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 investmentâ€™s overall performance.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (74.4%) in the period of the last 5 years, the total return, or increase in value of -6.5% of Global X Fertilizers/Potash ETF is lower, thus worse.
- Looking at total return, or performance in of -1.6% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (48.6%).

'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:- Compared with the benchmark SPY (11.8%) in the period of the last 5 years, the annual performance (CAGR) of -1.4% of Global X Fertilizers/Potash ETF is lower, thus worse.
- Looking at annual performance (CAGR) in of -0.6% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (14.1%).

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (13.5%) in the period of the last 5 years, the 30 days standard deviation of 17.6% of Global X Fertilizers/Potash ETF is greater, thus worse.
- During the last 3 years, the 30 days standard deviation is 15.6%, which is greater, thus worse than the value of 12.8% 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.'

Using this definition on our asset we see for example:- Looking at the downside risk of 18.4% 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 (14.8%)
- Looking at downside deviation in of 16.2% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (14.6%).

'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 (0.69) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of -0.22 of Global X Fertilizers/Potash ETF is smaller, thus worse.
- During the last 3 years, the Sharpe Ratio is -0.2, which is lower, thus worse than the value of 0.91 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 -0.21 in the last 5 years of Global X Fertilizers/Potash ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.63)
- Compared with SPY (0.79) in the period of the last 3 years, the downside risk / excess return profile of -0.19 is smaller, 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.'

Which means for our asset as example:- Compared with the benchmark SPY (3.99 ) in the period of the last 5 years, the Ulcer Index of 17 of Global X Fertilizers/Potash ETF is larger, thus worse.
- Looking at Downside risk index in of 10 in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (4.09 ).

'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:- Looking at the maximum reduction from previous high of -34 days in the last 5 years of Global X Fertilizers/Potash ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (-19.3 days)
- Compared with SPY (-19.3 days) in the period of the last 3 years, the maximum drop from peak to valley of -22.8 days is smaller, thus worse.

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (187 days) in the period of the last 5 years, the maximum days below previous high of 1158 days of Global X Fertilizers/Potash ETF is larger, thus worse.
- Looking at maximum days below previous high in of 462 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (139 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:- Looking at the average days under water of 566 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 (42 days)
- Compared with SPY (36 days) in the period of the last 3 years, the average days under water of 169 days is higher, thus worse.
