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:
  • The total return, or performance over 5 years of Vanguard Short Term Treasury Fund is 3.2%, which is lower, thus worse compared to the benchmark SPY (101.9%) in the same period.
  • Looking at total return in of 1.6% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (33.5%).

CAGR:

'The compound annual growth rate isn't a true return rate, but rather a representational figure. It is essentially a number that describes the rate at which an investment would have grown if it had grown the same rate every year and the profits were reinvested at the end of each year. In reality, this sort of performance is unlikely. However, CAGR can be used to smooth returns so that they may be more easily understood when compared to alternative investments.'

Using this definition on our asset we see for example:
  • Looking at the annual return (CAGR) of 0.6% 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 (15.1%)
  • Compared with SPY (10.1%) in the period of the last 3 years, the annual performance (CAGR) of 0.5% is smaller, thus worse.

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 historical 30 days volatility over 5 years of Vanguard Short Term Treasury Fund is 2.5%, which is lower, thus better compared to the benchmark SPY (21%) in the same period.
  • Compared with SPY (17.5%) in the period of the last 3 years, the volatility of 3% is lower, thus better.

DownVol:

'The downside volatility is similar to the volatility, or standard deviation, but only takes losing/negative periods into account.'

Applying this definition to our asset in some examples:
  • The downside deviation over 5 years of Vanguard Short Term Treasury Fund is 1.7%, which is smaller, thus better compared to the benchmark SPY (15%) in the same period.
  • Looking at downside volatility in of 2% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (12.3%).

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 Vanguard Short Term Treasury Fund is -0.74, which is lower, thus worse compared to the benchmark SPY (0.6) in the same period.
  • Compared with SPY (0.44) in the period of the last 3 years, the risk / return profile (Sharpe) of -0.65 is smaller, thus worse.

Sortino:

'The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally. Though both ratios measure an investment's risk-adjusted return, they do so in significantly different ways that will frequently lead to differing conclusions as to the true nature of the investment's return-generating efficiency. The Sortino ratio is used as a way to compare the risk-adjusted performance of programs with differing risk and return profiles. In general, risk-adjusted returns seek to normalize the risk across programs and then see which has the higher return unit per risk.'

Which means for our asset as example:
  • The downside risk / excess return profile over 5 years of Vanguard Short Term Treasury Fund is -1.09, which is lower, thus worse compared to the benchmark SPY (0.84) in the same period.
  • Compared with SPY (0.62) in the period of the last 3 years, the ratio of annual return and downside deviation of -1 is smaller, thus worse.

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (9.32 ) in the period of the last 5 years, the Ulcer Index of 4.07 of Vanguard Short Term Treasury Fund is smaller, thus better.
  • Compared with SPY (10 ) in the period of the last 3 years, the Ulcer Ratio of 3.15 is smaller, thus better.

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 reduction from previous high of -8.2 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 (-33.7 days)
  • Compared with SPY (-24.5 days) in the period of the last 3 years, the maximum drop from peak to valley of -6 days is greater, thus better.

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:
  • The maximum days below previous high over 5 years of Vanguard Short Term Treasury Fund is 946 days, which is larger, thus worse compared to the benchmark SPY (488 days) in the same period.
  • Looking at maximum days below previous high in of 628 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (488 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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (122 days) in the period of the last 5 years, the average time in days below previous high water mark of 389 days of Vanguard Short Term Treasury Fund is greater, thus worse.
  • Looking at average days below previous high in of 275 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (177 days).
