Statistics (YTD)

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

TotalReturn:

'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:
  • The total return, or increase in value over 5 years of iShares North American Natural Resources ETF is 39.5%, which is lower, thus worse compared to the benchmark SPY (63%) in the same period.
  • During the last 3 years, the total return is 65.4%, which is higher, thus better than the value of 33.5% from the benchmark.

CAGR:

'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 compounded annual growth rate (CAGR) of 6.9% in the last 5 years of iShares North American Natural Resources ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (10.3%)
  • Compared with SPY (10.1%) in the period of the last 3 years, the annual performance (CAGR) of 18.2% is larger, thus better.

Volatility:

'In finance, volatility (symbol σ) is the degree of variation of a trading price series over time as measured by the standard deviation of logarithmic returns. Historic volatility measures a time series of past market prices. Implied volatility looks forward in time, being derived from the market price of a market-traded derivative (in particular, an option). Commonly, the higher the volatility, the riskier the security.'

Which means for our asset as example:
  • The volatility over 5 years of iShares North American Natural Resources ETF is 30.2%, which is larger, thus worse compared to the benchmark SPY (21.6%) in the same period.
  • Compared with SPY (25.1%) in the period of the last 3 years, the 30 days standard deviation of 35.8% is higher, thus worse.

DownVol:

'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.'

Which means for our asset as example:
  • The downside volatility over 5 years of iShares North American Natural Resources ETF is 22.2%, which is larger, thus worse compared to the benchmark SPY (15.6%) in the same period.
  • Looking at downside deviation in of 26.2% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (18.1%).

Sharpe:

'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.'

Applying this definition to our asset in some examples:
  • The ratio of return and volatility (Sharpe) over 5 years of iShares North American Natural Resources ETF is 0.15, which is smaller, thus worse compared to the benchmark SPY (0.36) in the same period.
  • Compared with SPY (0.3) in the period of the last 3 years, the risk / return profile (Sharpe) of 0.44 is greater, thus better.

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:
  • The excess return divided by the downside deviation over 5 years of iShares North American Natural Resources ETF is 0.2, which is lower, thus worse compared to the benchmark SPY (0.5) in the same period.
  • Looking at excess return divided by the downside deviation in of 0.6 in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (0.42).

Ulcer:

'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 Ulcer Ratio over 5 years of iShares North American Natural Resources ETF is 21 , which is greater, thus worse compared to the benchmark SPY (8.88 ) in the same period.
  • Looking at Ulcer Ratio in of 15 in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (11 ).

MaxDD:

'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.'

Which means for our asset as example:
  • Looking at the maximum drop from peak to valley of -60.6 days in the last 5 years of iShares North American Natural Resources ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (-33.7 days)
  • Looking at maximum reduction from previous high in of -50.9 days in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (-33.7 days).

MaxDuration:

'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 time in days below previous high water mark of 914 days in the last 5 years of iShares North American Natural Resources ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (273 days)
  • Looking at maximum days under water in of 254 days in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (273 days).

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.'

Using this definition on our asset we see for example:
  • The average days below previous high over 5 years of iShares North American Natural Resources ETF is 357 days, which is higher, thus worse compared to the benchmark SPY (57 days) in the same period.
  • During the last 3 years, the average time in days below previous high water mark is 75 days, which is greater, thus worse than the value of 73 days from the benchmark.
