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:
  • Compared with the benchmark SPY (74.2%) in the period of the last 5 years, the total return of 74.2% of SPDR S&P 500 is higher, thus better.
  • Looking at total return, or increase in value in of 50.1% in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (50.1%).

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:
  • Looking at the annual performance (CAGR) of 11.8% in the last 5 years of SPDR S&P 500, we see it is relatively larger, thus better in comparison to the benchmark SPY (11.8%)
  • Compared with SPY (14.5%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of 14.5% is higher, thus better.

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:
  • The historical 30 days volatility over 5 years of SPDR S&P 500 is 13.3%, which is larger, thus worse compared to the benchmark SPY (13.3%) in the same period.
  • Compared with SPY (13%) in the period of the last 3 years, the historical 30 days volatility of 13% is higher, thus worse.

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.'

Using this definition on our asset we see for example:
  • Looking at the downside volatility of 9.6% in the last 5 years of SPDR S&P 500, we see it is relatively higher, thus worse in comparison to the benchmark SPY (9.6%)
  • Compared with SPY (9.4%) in the period of the last 3 years, the downside deviation of 9.4% is higher, thus worse.

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 0.69 in the last 5 years of SPDR S&P 500, we see it is relatively larger, thus better in comparison to the benchmark SPY (0.69)
  • Looking at Sharpe Ratio in of 0.93 in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (0.93).

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:
  • Looking at the downside risk / excess return profile of 0.96 in the last 5 years of SPDR S&P 500, we see it is relatively greater, thus better in comparison to the benchmark SPY (0.96)
  • During the last 3 years, the downside risk / excess return profile is 1.27, which is higher, thus better than the value of 1.27 from the benchmark.

Ulcer:

'Ulcer Index is a method for measuring investment risk that addresses the real concerns of investors, unlike the widely used standard deviation of return. UI is a measure of the depth and duration of drawdowns in prices from earlier highs. Using Ulcer Index instead of standard deviation can lead to very different conclusions about investment risk and risk-adjusted return, especially when evaluating strategies that seek to avoid major declines in portfolio value (market timing, dynamic asset allocation, hedge funds, etc.). The Ulcer Index was originally developed in 1987. Since then, it has been widely recognized and adopted by the investment community. According to Nelson Freeburg, editor of Formula Research, Ulcer Index is “perhaps the most fully realized statistical portrait of risk there is.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (3.97 ) in the period of the last 5 years, the Ulcer Ratio of 3.97 of SPDR S&P 500 is greater, thus worse.
  • Compared with SPY (4.1 ) in the period of the last 3 years, the Ulcer Ratio of 4.1 is larger, thus worse.

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:
  • Compared with the benchmark SPY (-19.3 days) in the period of the last 5 years, the maximum reduction from previous high of -19.3 days of SPDR S&P 500 is larger, thus better.
  • Compared with SPY (-19.3 days) in the period of the last 3 years, the maximum drop from peak to valley of -19.3 days is larger, thus better.

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) in days.'

Which means for our asset as example:
  • Looking at the maximum days under water of 187 days in the last 5 years of SPDR S&P 500, we see it is relatively higher, thus worse in comparison to the benchmark SPY (187 days)
  • Looking at maximum days below previous high in of 139 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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (42 days) in the period of the last 5 years, the average days below previous high of 42 days of SPDR S&P 500 is larger, thus worse.
  • Compared with SPY (37 days) in the period of the last 3 years, the average days below previous high of 37 days is higher, thus worse.
