'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (68.1%) in the period of the last 5 years, the total return, or increase in value of -79.2% of ProShares UltraShort Basic Materials is lower, thus worse.
- Looking at total return, or performance in of -74.1% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (47%).

'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 (11%) in the period of the last 5 years, the annual return (CAGR) of -27% of ProShares UltraShort Basic Materials is lower, thus worse.
- Looking at annual performance (CAGR) in of -36.3% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (13.7%).

'Volatility is a rate at which the price of a security increases or decreases for a given set of returns. Volatility is measured by calculating the standard deviation of the annualized returns over a given period of time. It shows the range to which the price of a security may increase or decrease. Volatility measures the risk of a security. It is used in option pricing formula to gauge the fluctuations in the returns of the underlying assets. Volatility indicates the pricing behavior of the security and helps estimate the fluctuations that may happen in a short period of time.'

Using this definition on our asset we see for example:- Looking at the historical 30 days volatility of 51% in the last 5 years of ProShares UltraShort Basic Materials, we see it is relatively greater, thus worse in comparison to the benchmark SPY (21.4%)
- During the last 3 years, the historical 30 days volatility is 46.7%, which is greater, thus worse than the value of 18.7% 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.'

Which means for our asset as example:- Looking at the downside volatility of 35.7% in the last 5 years of ProShares UltraShort Basic Materials, we see it is relatively larger, thus worse in comparison to the benchmark SPY (15.4%)
- During the last 3 years, the downside volatility is 33.2%, which is larger, thus worse than the value of 13.3% from the benchmark.

'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:- The risk / return profile (Sharpe) over 5 years of ProShares UltraShort Basic Materials is -0.58, which is lower, thus worse compared to the benchmark SPY (0.4) in the same period.
- During the last 3 years, the Sharpe Ratio is -0.83, which is lower, thus worse than the value of 0.6 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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (0.55) in the period of the last 5 years, the ratio of annual return and downside deviation of -0.82 of ProShares UltraShort Basic Materials is lower, thus worse.
- Looking at excess return divided by the downside deviation in of -1.17 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.84).

'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.'

Using this definition on our asset we see for example:- The Downside risk index over 5 years of ProShares UltraShort Basic Materials is 68 , which is higher, thus worse compared to the benchmark SPY (9.45 ) in the same period.
- Looking at Ulcer Ratio in of 64 in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (10 ).

'Maximum drawdown measures the loss in any losing period during a fund’s investment record. It is defined as the percent retrenchment from a fund’s peak value to the fund’s valley value. The drawdown is in effect from the time the fund’s retrenchment begins until a new fund high is reached. The maximum drawdown encompasses both the period from the fund’s peak to the fund’s valley (length), and the time from the fund’s valley to a new fund high (recovery). It measures the largest percentage drawdown that has occurred in any fund’s data record.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum reduction from previous high of -91.5 days of ProShares UltraShort Basic Materials is lower, thus worse.
- During the last 3 years, the maximum DrawDown is -79.2 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). Many assume Max DD Duration is the length of time between new highs during which the Max DD (magnitude) occurred. But that isn’t always the case. The Max DD duration is the longest time between peaks, period. So it could be the time when the program also had its biggest peak to valley loss (and usually is, because the program needs a long time to recover from the largest loss), but it doesn’t have to be'

Which means for our asset as example:- Compared with the benchmark SPY (351 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 801 days of ProShares UltraShort Basic Materials is greater, thus worse.
- Looking at maximum days under water in of 757 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (351 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.'

Which means for our asset as example:- Compared with the benchmark SPY (78 days) in the period of the last 5 years, the average days under water of 300 days of ProShares UltraShort Basic Materials is greater, thus worse.
- Looking at average days below previous high in of 379 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (101 days).
