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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (63%) in the period of the last 5 years, the total return of 3.8% of Vanguard Total Bond Market Index Fund is lower, thus worse.
  • During the last 3 years, the total return, or performance is -7.7%, which is lower, thus worse 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:
  • Compared with the benchmark SPY (10.3%) in the period of the last 5 years, the annual return (CAGR) of 0.8% of Vanguard Total Bond Market Index Fund is lower, thus worse.
  • Compared with SPY (10.1%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of -2.6% is lower, thus worse.

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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (21.6%) in the period of the last 5 years, the volatility of 5% of Vanguard Total Bond Market Index Fund is lower, thus better.
  • During the last 3 years, the volatility is 5.9%, which is smaller, thus better than the value of 25.1% 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:
  • Compared with the benchmark SPY (15.6%) in the period of the last 5 years, the downside deviation of 3.6% of Vanguard Total Bond Market Index Fund is smaller, thus better.
  • Compared with SPY (18.1%) in the period of the last 3 years, the downside deviation of 4.3% is lower, thus better.

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:
  • Compared with the benchmark SPY (0.36) in the period of the last 5 years, the Sharpe Ratio of -0.35 of Vanguard Total Bond Market Index Fund is lower, thus worse.
  • Compared with SPY (0.3) in the period of the last 3 years, the risk / return profile (Sharpe) of -0.88 is lower, 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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (0.5) in the period of the last 5 years, the ratio of annual return and downside deviation of -0.49 of Vanguard Total Bond Market Index Fund is lower, thus worse.
  • During the last 3 years, the downside risk / excess return profile is -1.19, which is lower, thus worse than the value of 0.42 from the benchmark.

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.'

Which means for our asset as example:
  • The Downside risk index over 5 years of Vanguard Total Bond Market Index Fund is 6.03 , which is smaller, thus better compared to the benchmark SPY (8.88 ) in the same period.
  • During the last 3 years, the Downside risk index is 7.75 , which is lower, thus better than the value of 11 from the benchmark.

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 -19.1 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)
  • Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum drop from peak to valley of -19.1 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:
  • Looking at the maximum days under water of 630 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 (273 days)
  • Compared with SPY (273 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 630 days is larger, thus worse.

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 (57 days) in the period of the last 5 years, the average time in days below previous high water mark of 199 days of Vanguard Total Bond Market Index Fund is larger, thus worse.
  • Compared with SPY (73 days) in the period of the last 3 years, the average days below previous high of 277 days is greater, thus worse.
