'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 (60.9%) in the period of the last 5 years, the total return, or increase in value of -7.7% of SPDR DJ Wilshire Intl Real Estate is lower, thus worse.
- During the last 3 years, the total return is -9.1%, which is smaller, thus worse than the value of 34.2% from the benchmark.

'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 (10%) in the period of the last 5 years, the annual return (CAGR) of -1.6% of SPDR DJ Wilshire Intl Real Estate is lower, thus worse.
- Compared with SPY (10.3%) in the period of the last 3 years, the annual return (CAGR) of -3.1% is smaller, thus worse.

'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.'

Using this definition on our asset we see for example:- The volatility over 5 years of SPDR DJ Wilshire Intl Real Estate is 17.2%, which is lower, thus better compared to the benchmark SPY (18.7%) in the same period.
- Looking at historical 30 days volatility in of 18.1% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (21.5%).

'The downside volatility is similar to the volatility, or standard deviation, but only takes losing/negative periods into account.'

Using this definition on our asset we see for example:- The downside volatility over 5 years of SPDR DJ Wilshire Intl Real Estate is 13.3%, which is lower, thus better compared to the benchmark SPY (13.6%) in the same period.
- Looking at downside deviation in of 14.1% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (15.7%).

'The Sharpe ratio was developed by Nobel laureate William F. Sharpe, and is used to help investors understand the return of an investment compared to its risk. The ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk. Subtracting the risk-free rate from the mean return allows an investor to better isolate the profits associated with risk-taking activities. One intuition of this calculation is that a portfolio engaging in 'zero risk' investments, such as the purchase of U.S. Treasury bills (for which the expected return is the risk-free rate), has a Sharpe ratio of exactly zero. Generally, the greater the value of the Sharpe ratio, the more attractive the risk-adjusted return.'

Which means for our asset as example:- Looking at the Sharpe Ratio of -0.24 in the last 5 years of SPDR DJ Wilshire Intl Real Estate, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.4)
- During the last 3 years, the ratio of return and volatility (Sharpe) is -0.31, which is lower, thus worse than the value of 0.36 from the benchmark.

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (0.55) in the period of the last 5 years, the ratio of annual return and downside deviation of -0.31 of SPDR DJ Wilshire Intl Real Estate is lower, thus worse.
- Compared with SPY (0.5) in the period of the last 3 years, the excess return divided by the downside deviation of -0.4 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.'

Applying this definition to our asset in some examples:- Looking at the Downside risk index of 8.79 in the last 5 years of SPDR DJ Wilshire Intl Real Estate, we see it is relatively higher, thus worse in comparison to the benchmark SPY (5.82 )
- During the last 3 years, the Downside risk index is 9.91 , which is greater, thus worse than the value of 6.86 from the benchmark.

'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.'

Using this definition on our asset we see for example:- Looking at the maximum drop from peak to valley of -43.4 days in the last 5 years of SPDR DJ Wilshire Intl Real Estate, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (-33.7 days)
- Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum drop from peak to valley of -43.4 days is lower, 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.'

Applying this definition to our asset in some examples:- Looking at the maximum days under water of 418 days in the last 5 years of SPDR DJ Wilshire Intl Real Estate, we see it is relatively greater, thus worse in comparison to the benchmark SPY (187 days)
- Looking at maximum days under water in of 418 days in the period of the last 3 years, we see it is relatively higher, 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:- The average days under water over 5 years of SPDR DJ Wilshire Intl Real Estate is 135 days, which is higher, thus worse compared to the benchmark SPY (43 days) in the same period.
- During the last 3 years, the average days under water is 132 days, which is larger, thus worse than the value of 39 days from the benchmark.
