'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (110.3%) in the period of the last 5 years, the total return, or increase in value of % of Global X Data Center REITs & Digital Infrastructure ETF is lower, thus worse.
- During the last 3 years, the total return, or increase in value is 10.2%, which is smaller, thus worse than the value of 39.7% from the benchmark.

'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.'

Which means for our asset as example:- Looking at the annual performance (CAGR) of % in the last 5 years of Global X Data Center REITs & Digital Infrastructure ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (16.1%)
- During the last 3 years, the compounded annual growth rate (CAGR) is 3.3%, which is lower, thus worse than the value of 11.8% 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:- Looking at the historical 30 days volatility of % in the last 5 years of Global X Data Center REITs & Digital Infrastructure ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (20.9%)
- During the last 3 years, the volatility is 21.6%, which is higher, thus worse than the value of 17.5% from the benchmark.

'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:- Looking at the downside risk of % in the last 5 years of Global X Data Center REITs & Digital Infrastructure ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (14.9%)
- Compared with SPY (12.2%) in the period of the last 3 years, the downside volatility of 14.8% is larger, thus worse.

'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 (0.65) in the period of the last 5 years, the Sharpe Ratio of of Global X Data Center REITs & Digital Infrastructure ETF is lower, thus worse.
- Looking at Sharpe Ratio in of 0.04 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.53).

'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:- Looking at the downside risk / excess return profile of in the last 5 years of Global X Data Center REITs & Digital Infrastructure ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.91)
- During the last 3 years, the excess return divided by the downside deviation is 0.05, which is smaller, thus worse than the value of 0.76 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 Ulcer Index of in the last 5 years of Global X Data Center REITs & Digital Infrastructure ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (9.32 )
- Looking at Ulcer Ratio in of 21 in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (10 ).

'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.'

Which means for our asset as example:- Looking at the maximum DrawDown of days in the last 5 years of Global X Data Center REITs & Digital Infrastructure ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (-33.7 days)
- During the last 3 years, the maximum reduction from previous high is -39 days, which is lower, thus worse than the value of -24.5 days from the benchmark.

'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:- Looking at the maximum days below previous high of days in the last 5 years of Global X Data Center REITs & Digital Infrastructure ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (488 days)
- During the last 3 years, the maximum days below previous high is 696 days, which is greater, thus worse than the value of 488 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.'

Using this definition on our asset we see for example:- Looking at the average days under water of days in the last 5 years of Global X Data Center REITs & Digital Infrastructure ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (124 days)
- Compared with SPY (179 days) in the period of the last 3 years, the average days under water of 330 days is higher, thus worse.
