Statistics (YTD)

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

TotalReturn:

'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:
  • Looking at the total return, or increase in value of 7.2% in the last 5 years of Vanguard Short Term Treasury Fund, we see it is relatively lower, thus worse in comparison to the benchmark SPY (77.1%)
  • Compared with SPY (51.7%) in the period of the last 3 years, the total return of 5.6% is lower, thus worse.

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (12.1%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of 1.4% of Vanguard Short Term Treasury Fund is lower, thus worse.
  • Looking at annual return (CAGR) in of 1.8% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (14.9%).

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.'

Applying this definition to our asset in some examples:
  • Looking at the historical 30 days volatility of 1.4% in the last 5 years of Vanguard Short Term Treasury Fund, we see it is relatively lower, thus better in comparison to the benchmark SPY (13.3%)
  • Compared with SPY (13%) in the period of the last 3 years, the 30 days standard deviation of 1.4% is lower, thus better.

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:
  • Compared with the benchmark SPY (9.6%) in the period of the last 5 years, the downside risk of 0.9% of Vanguard Short Term Treasury Fund is smaller, thus better.
  • During the last 3 years, the downside deviation is 0.8%, which is smaller, thus better than the value of 9.4% from the benchmark.

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:
  • Looking at the risk / return profile (Sharpe) of -0.79 in the last 5 years of Vanguard Short Term Treasury Fund, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (0.72)
  • During the last 3 years, the Sharpe Ratio is -0.49, which is smaller, thus worse than the value of 0.96 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:
  • The downside risk / excess return profile over 5 years of Vanguard Short Term Treasury Fund is -1.25, which is lower, thus worse compared to the benchmark SPY (1) in the same period.
  • Looking at ratio of annual return and downside deviation in of -0.81 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (1.32).

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:
  • Looking at the Downside risk index of 0.55 in the last 5 years of Vanguard Short Term Treasury Fund, we see it is relatively smaller, thus better in comparison to the benchmark SPY (3.97 )
  • During the last 3 years, the Ulcer Index is 0.61 , which is smaller, thus better than the value of 4.1 from the benchmark.

MaxDD:

'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.'

Applying this definition to our asset in some examples:
  • Looking at the maximum reduction from previous high of -1.4 days in the last 5 years of Vanguard Short Term Treasury Fund, we see it is relatively larger, thus better in comparison to the benchmark SPY (-19.3 days)
  • Looking at maximum DrawDown in of -1.4 days in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (-19.3 days).

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'

Applying this definition to our asset in some examples:
  • The maximum days below previous high over 5 years of Vanguard Short Term Treasury Fund is 320 days, which is larger, thus worse compared to the benchmark SPY (187 days) in the same period.
  • Looking at maximum time in days below previous high water mark in of 320 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (139 days).

AveDuration:

'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.'

Which means for our asset as example:
  • The average days under water over 5 years of Vanguard Short Term Treasury Fund is 89 days, which is larger, thus worse compared to the benchmark SPY (42 days) in the same period.
  • Looking at average days below previous high in of 87 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (37 days).
