'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:- The total return, or increase in value over 5 years of Global X Fertilizers/Potash ETF is -8.2%, which is smaller, thus worse compared to the benchmark SPY (68.2%) in the same period.
- Compared with SPY (47.7%) in the period of the last 3 years, the total return of 10.2% is smaller, thus worse.

'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 annual return (CAGR) over 5 years of Global X Fertilizers/Potash ETF is -1.7%, which is smaller, thus worse compared to the benchmark SPY (11%) in the same period.
- Looking at compounded annual growth rate (CAGR) in of 3.3% in the period of the last 3 years, we see it is relatively smaller, 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.'

Using this definition on our asset we see for example:- Looking at the volatility of 16.9% 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 (13.2%)
- During the last 3 years, the volatility is 16.8%, which is greater, thus worse than the value of 12.4% 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:- Compared with the benchmark SPY (14.6%) in the period of the last 5 years, the downside risk of 17.7% of Global X Fertilizers/Potash ETF is higher, thus worse.
- During the last 3 years, the downside volatility is 17.4%, which is greater, 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:- Looking at the risk / return profile (Sharpe) of -0.25 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 (0.64)
- Compared with SPY (0.92) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of 0.05 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.'

Applying this definition to our asset in some examples:- The excess return divided by the downside deviation over 5 years of Global X Fertilizers/Potash ETF is -0.24, which is smaller, thus worse compared to the benchmark SPY (0.58) in the same period.
- Compared with SPY (0.81) in the period of the last 3 years, the excess return divided by the downside deviation of 0.04 is lower, thus worse.

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (3.95 ) in the period of the last 5 years, the Ulcer Ratio of 15 of Global X Fertilizers/Potash ETF is higher, thus better.
- Compared with SPY (4 ) in the period of the last 3 years, the Ulcer Ratio of 6.74 is higher, 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.'

Applying this definition to our asset in some examples:- The maximum DrawDown over 5 years of Global X Fertilizers/Potash ETF is -34 days, which is smaller, thus worse compared to the benchmark SPY (-19.3 days) in the same period.
- Looking at maximum reduction from previous high in of -21.2 days in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (-19.3 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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (187 days) in the period of the last 5 years, the maximum days below previous high of 964 days of Global X Fertilizers/Potash ETF is greater, thus worse.
- Compared with SPY (131 days) in the period of the last 3 years, the maximum days below previous high of 288 days is larger, thus worse.

'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 under water over 5 years of Global X Fertilizers/Potash ETF is 387 days, which is larger, 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 94 days is higher, thus worse.
