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.'

Which means for our asset as example:
  • The total return, or increase in value over 5 years of Comcast is 46%, which is smaller, thus worse compared to the benchmark SPY (66.6%) in the same period.
  • During the last 3 years, the total return, or performance is 8.6%, which is lower, thus worse than the value of 36.1% from the benchmark.

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:
  • The compounded annual growth rate (CAGR) over 5 years of Comcast is 7.9%, which is lower, thus worse compared to the benchmark SPY (10.8%) in the same period.
  • Looking at compounded annual growth rate (CAGR) in of 2.8% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (10.8%).

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:
  • Looking at the 30 days standard deviation of 25.5% in the last 5 years of Comcast, we see it is relatively higher, thus worse in comparison to the benchmark SPY (19%)
  • During the last 3 years, the 30 days standard deviation is 29.3%, which is greater, thus worse than the value of 22% 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.'

Using this definition on our asset we see for example:
  • The downside deviation over 5 years of Comcast is 17.9%, which is larger, thus worse compared to the benchmark SPY (13.9%) in the same period.
  • Looking at downside deviation in of 20.7% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (16.2%).

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 Comcast is 0.21, which is lower, thus worse compared to the benchmark SPY (0.43) in the same period.
  • Looking at Sharpe Ratio in of 0.01 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.38).

Sortino:

'The Sortino ratio, a variation of the Sharpe ratio only factors in the downside, or negative volatility, rather than the total volatility used in calculating the Sharpe ratio. The theory behind the Sortino variation is that upside volatility is a plus for the investment, and it, therefore, should not be included in the risk calculation. Therefore, the Sortino ratio takes upside volatility out of the equation and uses only the downside standard deviation in its calculation instead of the total standard deviation that is used in calculating the Sharpe ratio.'

Which means for our asset as example:
  • The downside risk / excess return profile over 5 years of Comcast is 0.3, which is lower, thus worse compared to the benchmark SPY (0.59) in the same period.
  • Looking at excess return divided by the downside deviation in of 0.01 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.52).

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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (5.9 ) in the period of the last 5 years, the Ulcer Ratio of 11 of Comcast is higher, thus worse.
  • During the last 3 years, the Ulcer Index is 13 , which is larger, thus worse than the value of 6.98 from the benchmark.

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 (-33.7 days) in the period of the last 5 years, the maximum reduction from previous high of -31.3 days of Comcast is larger, thus better.
  • Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum reduction from previous high of -31.3 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.'

Applying this definition to our asset in some examples:
  • The maximum days below previous high over 5 years of Comcast is 307 days, which is greater, thus worse compared to the benchmark SPY (187 days) in the same period.
  • During the last 3 years, the maximum days below previous high is 307 days, which is larger, thus worse than the value of 139 days from the benchmark.

AveDuration:

'The Average 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. 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 (44 days) in the period of the last 5 years, the average days under water of 78 days of Comcast is greater, thus worse.
  • During the last 3 years, the average days below previous high is 89 days, which is higher, thus worse than the value of 41 days from the benchmark.

Returns (%)

  • Note that yearly returns do not equal the sum of monthly returns due to compounding.
  • Performance results of Comcast are hypothetical, do not account for slippage, fees or taxes, and are based on backtesting, which has many inherent limitations, some of which are described in our Terms of Use.
