'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:- Looking at the total return, or increase in value of -73.4% in the last 5 years of ProShares UltraShort Health Care, we see it is relatively lower, thus worse in comparison to the benchmark SPY (66.2%)
- Looking at total return, or performance in of -52.5% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (47.5%).

'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 -23.3% in the last 5 years of ProShares UltraShort Health Care, we see it is relatively lower, thus worse in comparison to the benchmark SPY (10.7%)
- During the last 3 years, the annual return (CAGR) is -22%, which is smaller, thus worse than the value of 13.9% 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 30 days standard deviation of 30.9% in the last 5 years of ProShares UltraShort Health Care, we see it is relatively higher, thus worse in comparison to the benchmark SPY (13.3%)
- Looking at 30 days standard deviation in of 28.9% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (12.5%).

'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:- Compared with the benchmark SPY (14.6%) in the period of the last 5 years, the downside risk of 32.4% of ProShares UltraShort Health Care is higher, thus worse.
- Looking at downside risk in of 31.3% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (14.2%).

'The Sharpe ratio is the measure of risk-adjusted return of a financial portfolio. Sharpe ratio is a measure of excess portfolio return over the risk-free rate relative to its standard deviation. Normally, the 90-day Treasury bill rate is taken as the proxy for risk-free rate. A portfolio with a higher Sharpe ratio is considered superior relative to its peers. The measure was named after William F Sharpe, a Nobel laureate and professor of finance, emeritus at Stanford University.'

Which means for our asset as example:- Looking at the risk / return profile (Sharpe) of -0.84 in the last 5 years of ProShares UltraShort Health Care, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.62)
- During the last 3 years, the risk / return profile (Sharpe) is -0.85, which is smaller, thus worse than the value of 0.91 from the benchmark.

'The Sortino ratio, a variation of the Sharpe ratio only factors in the downside, or negative volatility, rather than the total volatility used in calculating the Sharpe ratio. The theory behind the Sortino variation is that upside volatility is a plus for the investment, and it, therefore, should not be included in the risk calculation. Therefore, the Sortino ratio takes upside volatility out of the equation and uses only the downside standard deviation in its calculation instead of the total standard deviation that is used in calculating the Sharpe ratio.'

Which means for our asset as example:- Compared with the benchmark SPY (0.56) in the period of the last 5 years, the ratio of annual return and downside deviation of -0.8 of ProShares UltraShort Health Care is lower, thus worse.
- Compared with SPY (0.8) in the period of the last 3 years, the downside risk / excess return profile of -0.78 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.'

Which means for our asset as example:- Compared with the benchmark SPY (3.96 ) in the period of the last 5 years, the Ulcer Ratio of 55 of ProShares UltraShort Health Care is higher, thus better.
- Compared with SPY (4.01 ) in the period of the last 3 years, the Downside risk index of 40 is higher, thus better.

'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 -76.2 days in the last 5 years of ProShares UltraShort Health Care, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (-19.3 days)
- Looking at maximum DrawDown in of -58.7 days in the period of the last 3 years, we see it is relatively lower, 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:- The maximum days below previous high over 5 years of ProShares UltraShort Health Care is 1257 days, which is larger, thus worse compared to the benchmark SPY (187 days) in the same period.
- Compared with SPY (139 days) in the period of the last 3 years, the maximum days below previous high of 637 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 below previous high over 5 years of ProShares UltraShort Health Care is 629 days, which is greater, thus worse compared to the benchmark SPY (41 days) in the same period.
- During the last 3 years, the average time in days below previous high water mark is 276 days, which is greater, thus worse than the value of 36 days from the benchmark.
