The index seeks to measure the performance of certain companies in the technology sector of the U.S. equity market. The fund is non-diversified.

Statistics (YTD)

What do these metrics mean? [Read More] [Hide]

TotalReturn:

'Total return is the amount of value an investor earns from a security over a specific period, typically one year, when all distributions are reinvested. Total return is expressed as a percentage of the amount invested. For example, a total return of 20% means the security increased by 20% of its original value due to a price increase, distribution of dividends (if a stock), coupons (if a bond) or capital gains (if a fund). Total return is a strong measure of an investment’s overall performance.'

Which means for our asset as example:
  • Looking at the total return, or performance of -96.6% in the last 5 years of ProShares UltraShort Technology, we see it is relatively lower, thus worse in comparison to the benchmark SPY (114.2%)
  • Compared with SPY (46.4%) in the period of the last 3 years, the total return, or performance of -87.8% is smaller, thus worse.

CAGR:

'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.'

Applying this definition to our asset in some examples:
  • Looking at the annual performance (CAGR) of -49.2% in the last 5 years of ProShares UltraShort Technology, we see it is relatively lower, thus worse in comparison to the benchmark SPY (16.5%)
  • Looking at compounded annual growth rate (CAGR) in of -50.3% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (13.5%).

Volatility:

'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 30 days standard deviation over 5 years of ProShares UltraShort Technology is 44.9%, which is larger, thus worse compared to the benchmark SPY (18.7%) in the same period.
  • Compared with SPY (22.6%) in the period of the last 3 years, the volatility of 53.2% is larger, thus worse.

DownVol:

'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 risk over 5 years of ProShares UltraShort Technology is 31.9%, which is greater, thus worse compared to the benchmark SPY (13.6%) in the same period.
  • During the last 3 years, the downside deviation is 37.7%, which is higher, thus worse than the value of 16.5% from the benchmark.

Sharpe:

'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 -1.15 in the last 5 years of ProShares UltraShort Technology, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.75)
  • During the last 3 years, the ratio of return and volatility (Sharpe) is -0.99, which is lower, thus worse than the value of 0.49 from the benchmark.

Sortino:

'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.'

Applying this definition to our asset in some examples:
  • Looking at the excess return divided by the downside deviation of -1.62 in the last 5 years of ProShares UltraShort Technology, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (1.03)
  • During the last 3 years, the downside risk / excess return profile is -1.4, which is lower, thus worse than the value of 0.67 from the benchmark.

Ulcer:

'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.'

Using this definition on our asset we see for example:
  • The Ulcer Index over 5 years of ProShares UltraShort Technology is 72 , which is greater, thus worse compared to the benchmark SPY (5.58 ) in the same period.
  • Compared with SPY (6.91 ) in the period of the last 3 years, the Downside risk index of 57 is greater, thus worse.

MaxDD:

'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.'

Applying this definition to our asset in some examples:
  • The maximum DrawDown over 5 years of ProShares UltraShort Technology is -97 days, which is smaller, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
  • Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum drop from peak to valley of -91.1 days is lower, thus worse.

MaxDuration:

'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:
  • The maximum days below previous high over 5 years of ProShares UltraShort Technology is 1260 days, which is higher, thus worse compared to the benchmark SPY (139 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 547 days is higher, thus worse.

AveDuration:

'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.'

Applying this definition to our asset in some examples:
  • The average days under water over 5 years of ProShares UltraShort Technology is 631 days, which is larger, thus worse compared to the benchmark SPY (33 days) in the same period.
  • Looking at average days below previous high in of 222 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (36 days).
