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.'

Which means for our asset as example:
  • Looking at the total return of 22.6% in the last 5 years of Vanguard Total Bond Market Index Fund, we see it is relatively lower, thus worse in comparison to the benchmark SPY (88%)
  • During the last 3 years, the total return is 16.4%, which is lower, thus worse than the value of 39.5% from the benchmark.

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.'

Which means for our asset as example:
  • The annual return (CAGR) over 5 years of Vanguard Total Bond Market Index Fund is 4.2%, which is smaller, thus worse compared to the benchmark SPY (13.5%) in the same period.
  • During the last 3 years, the annual return (CAGR) is 5.2%, which is lower, thus worse than the value of 11.7% from the benchmark.

Volatility:

'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.'

Which means for our asset as example:
  • The 30 days standard deviation over 5 years of Vanguard Total Bond Market Index Fund is 3.7%, which is lower, thus better compared to the benchmark SPY (18.8%) in the same period.
  • During the last 3 years, the 30 days standard deviation is 3.9%, which is lower, thus better than the value of 22.3% from the benchmark.

DownVol:

'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 2.5% in the last 5 years of Vanguard Total Bond Market Index Fund, we see it is relatively smaller, thus better in comparison to the benchmark SPY (13.7%)
  • Looking at downside volatility in of 2.7% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (16.5%).

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 0.45 in the last 5 years of Vanguard Total Bond Market Index Fund, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.58)
  • Looking at ratio of return and volatility (Sharpe) in of 0.7 in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (0.41).

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.'

Applying this definition to our asset in some examples:
  • The excess return divided by the downside deviation over 5 years of Vanguard Total Bond Market Index Fund is 0.66, which is smaller, thus worse compared to the benchmark SPY (0.8) in the same period.
  • During the last 3 years, the ratio of annual return and downside deviation is 1.01, which is greater, thus better than the value of 0.56 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:
  • Looking at the Downside risk index of 1.7 in the last 5 years of Vanguard Total Bond Market Index Fund, we see it is relatively smaller, thus better in comparison to the benchmark SPY (5.79 )
  • Looking at Ulcer Index in of 1.38 in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (7.08 ).

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.'

Applying this definition to our asset in some examples:
  • Looking at the maximum DrawDown of -6.5 days in the last 5 years of Vanguard Total Bond Market Index Fund, we see it is relatively greater, thus better in comparison to the benchmark SPY (-33.7 days)
  • Looking at maximum reduction from previous high in of -6.5 days in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (-33.7 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:
  • Looking at the maximum days below previous high of 350 days in the last 5 years of Vanguard Total Bond Market Index Fund, we see it is relatively larger, thus worse in comparison to the benchmark SPY (139 days)
  • Looking at maximum time in days below previous high water mark in of 261 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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (37 days) in the period of the last 5 years, the average time in days below previous high water mark of 102 days of Vanguard Total Bond Market Index Fund is greater, thus worse.
  • Compared with SPY (45 days) in the period of the last 3 years, the average time in days below previous high water mark of 66 days is larger, thus worse.
