'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, or performance of 27.8% in the last 5 years of Global X Guru Index ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (59.2%)
- Looking at total return, or performance in of 27.7% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (33.1%).

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (9.7%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of 5% of Global X Guru Index ETF is lower, thus worse.
- During the last 3 years, the annual return (CAGR) is 8.5%, which is smaller, thus worse than the value of 10% from the benchmark.

'Volatility is a statistical measure of the dispersion of returns for a given security or market index. Volatility can either be measured by using the standard deviation or variance between returns from that same security or market index. Commonly, the higher the volatility, the riskier the security. In the securities markets, volatility is often associated with big swings in either direction. For example, when the stock market rises and falls more than one percent over a sustained period of time, it is called a 'volatile' market.'

Which means for our asset as example:- The 30 days standard deviation over 5 years of Global X Guru Index ETF is 19.9%, which is higher, thus worse compared to the benchmark SPY (18.7%) in the same period.
- Compared with SPY (21.5%) in the period of the last 3 years, the 30 days standard deviation of 21.9% is greater, thus worse.

'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.'

Which means for our asset as example:- Looking at the downside volatility of 14.8% in the last 5 years of Global X Guru Index ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (13.6%)
- Looking at downside deviation in of 16.3% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (15.7%).

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (0.39) in the period of the last 5 years, the Sharpe Ratio of 0.13 of Global X Guru Index ETF is smaller, thus worse.
- Looking at risk / return profile (Sharpe) in of 0.27 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.35).

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (0.53) in the period of the last 5 years, the downside risk / excess return profile of 0.17 of Global X Guru Index ETF is lower, thus worse.
- Looking at downside risk / excess return profile in of 0.37 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.48).

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (5.79 ) in the period of the last 5 years, the Ulcer Ratio of 11 of Global X Guru Index ETF is greater, thus worse.
- Looking at Downside risk index in of 7.66 in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (6.83 ).

'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:- The maximum reduction from previous high over 5 years of Global X Guru Index ETF is -37.4 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
- Looking at maximum DrawDown in of -37.4 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 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 under water of 488 days of Global X Guru Index ETF is higher, thus worse.
- During the last 3 years, the maximum days under water is 149 days, which is greater, 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 under water of 123 days in the last 5 years of Global X Guru Index ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (42 days)
- Looking at average time in days below previous high water mark in of 35 days in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (38 days).
