Statistics (YTD)

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

TotalReturn:

'Total return is the amount of value an investor earns from a security over a specific period, typically one year, when all distributions are reinvested. Total return is expressed as a percentage of the amount invested. For example, a total return of 20% means the security increased by 20% of its original value due to a price increase, distribution of dividends (if a stock), coupons (if a bond) or capital gains (if a fund). Total return is a strong measure of an investment’s overall performance.'

Using this definition on our asset we see for example:
  • The total return over 5 years of Vanguard Total Bond Market Index Fund is 17.3%, which is lower, thus worse compared to the benchmark SPY (77.1%) in the same period.
  • Compared with SPY (51.7%) in the period of the last 3 years, the total return, or performance of 14% 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.'

Using this definition on our asset we see for example:
  • The annual performance (CAGR) over 5 years of Vanguard Total Bond Market Index Fund is 3.2%, which is smaller, thus worse compared to the benchmark SPY (12.1%) in the same period.
  • During the last 3 years, the annual performance (CAGR) is 4.5%, which is lower, thus worse than the value of 14.9% from the benchmark.

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 volatility of 3.4% in the last 5 years of Vanguard Total Bond Market Index Fund, we see it is relatively lower, thus better in comparison to the benchmark SPY (13.3%)
  • During the last 3 years, the historical 30 days volatility is 3.1%, which is smaller, thus better than the value of 13% from the benchmark.

DownVol:

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

Using this definition on our asset we see for example:
  • Looking at the downside risk of 2.3% in the last 5 years of Vanguard Total Bond Market Index Fund, we see it is relatively lower, thus better in comparison to the benchmark SPY (9.6%)
  • Compared with SPY (9.4%) in the period of the last 3 years, the downside volatility of 2% is lower, thus better.

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.'

Using this definition on our asset we see for example:
  • The Sharpe Ratio over 5 years of Vanguard Total Bond Market Index Fund is 0.22, which is smaller, thus worse compared to the benchmark SPY (0.72) in the same period.
  • Compared with SPY (0.96) in the period of the last 3 years, the risk / return profile (Sharpe) of 0.64 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.'

Applying this definition to our asset in some examples:
  • Looking at the downside risk / excess return profile of 0.32 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 (1)
  • Looking at ratio of annual return and downside deviation in of 0.98 in the period of the last 3 years, we see it is relatively smaller, 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.'

Applying this definition to our asset in some examples:
  • Looking at the Downside risk index of 1.72 in the last 5 years of Vanguard Total Bond Market Index Fund, we see it is relatively lower, thus better in comparison to the benchmark SPY (3.97 )
  • Looking at Downside risk index in of 1.49 in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (4.1 ).

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:
  • The maximum reduction from previous high over 5 years of Vanguard Total Bond Market Index Fund is -4.7 days, which is higher, thus better compared to the benchmark SPY (-19.3 days) in the same period.
  • Looking at maximum DrawDown in of -3.6 days in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (-19.3 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:
  • Compared with the benchmark SPY (187 days) in the period of the last 5 years, the maximum days under water of 350 days of Vanguard Total Bond Market Index Fund is higher, thus worse.
  • During the last 3 years, the maximum days below previous high is 350 days, which is greater, thus worse than the value of 139 days from the benchmark.

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 below previous high over 5 years of Vanguard Total Bond Market Index Fund is 114 days, which is greater, thus worse compared to the benchmark SPY (42 days) in the same period.
  • Compared with SPY (37 days) in the period of the last 3 years, the average time in days below previous high water mark of 103 days is greater, thus worse.
