'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 (62.7%) in the period of the last 5 years, the total return of 11.7% of iShares S&P Global Timber & Forestry Index Fund is lower, thus worse.
- During the last 3 years, the total return, or increase in value is 26.1%, which is smaller, thus worse than the value of 34.7% 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:- Looking at the annual performance (CAGR) of 2.2% in the last 5 years of iShares S&P Global Timber & Forestry Index Fund, we see it is relatively lower, thus worse in comparison to the benchmark SPY (10.2%)
- During the last 3 years, the compounded annual growth rate (CAGR) is 8.1%, which is smaller, thus worse than the value of 10.5% 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:- Compared with the benchmark SPY (20.9%) in the period of the last 5 years, the historical 30 days volatility of 25.5% of iShares S&P Global Timber & Forestry Index Fund is higher, thus worse.
- Looking at volatility in of 29.9% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (24.1%).

'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 18.7% in the last 5 years of iShares S&P Global Timber & Forestry Index Fund, we see it is relatively higher, thus worse in comparison to the benchmark SPY (15.3%)
- Compared with SPY (17.6%) in the period of the last 3 years, the downside volatility of 21.8% 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 (0.37) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of -0.01 of iShares S&P Global Timber & Forestry Index Fund is lower, thus worse.
- During the last 3 years, the risk / return profile (Sharpe) is 0.19, which is smaller, thus worse than the value of 0.33 from the benchmark.

'The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally. Though both ratios measure an investment's risk-adjusted return, they do so in significantly different ways that will frequently lead to differing conclusions as to the true nature of the investment's return-generating efficiency. The Sortino ratio is used as a way to compare the risk-adjusted performance of programs with differing risk and return profiles. In general, risk-adjusted returns seek to normalize the risk across programs and then see which has the higher return unit per risk.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (0.51) in the period of the last 5 years, the excess return divided by the downside deviation of -0.01 of iShares S&P Global Timber & Forestry Index Fund is lower, thus worse.
- Compared with SPY (0.45) in the period of the last 3 years, the excess return divided by the downside deviation of 0.25 is smaller, 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:- The Ulcer Ratio over 5 years of iShares S&P Global Timber & Forestry Index Fund is 18 , which is greater, thus worse compared to the benchmark SPY (7.71 ) in the same period.
- During the last 3 years, the Downside risk index is 12 , which is higher, thus worse than the value of 9.08 from the benchmark.

'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.'

Using this definition on our asset we see for example:- Looking at the maximum reduction from previous high of -50.2 days in the last 5 years of iShares S&P Global Timber & Forestry Index Fund, 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 DrawDown of -40.6 days is lower, thus worse.

'The Maximum 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. It is the length of time the account was in the Max Drawdown. A Max Drawdown measures a retrenchment from when an equity curve reaches a new high. It’s the maximum an account lost during that retrenchment. This method is applied because a valley can’t be measured until a new high occurs. Once the new high is reached, the percentage change from the old high to the bottom of the largest trough is recorded.'

Applying this definition to our asset in some examples:- Looking at the maximum days under water of 637 days in the last 5 years of iShares S&P Global Timber & Forestry Index Fund, we see it is relatively greater, thus worse in comparison to the benchmark SPY (189 days)
- Looking at maximum days below previous high in of 354 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (189 days).

'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:- The average days under water over 5 years of iShares S&P Global Timber & Forestry Index Fund is 224 days, which is greater, thus worse compared to the benchmark SPY (46 days) in the same period.
- Looking at average time in days below previous high water mark in of 114 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (45 days).
