Statistics of Comcast (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:
  • Looking at the total return of 76.9% in the last 5 years of Comcast, we see it is relatively greater, thus better in comparison to the benchmark SPY (66%)
  • Compared with SPY (45.6%) in the period of the last 3 years, the total return, or increase in value of 39.5% 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 Comcast is 12.1%, which is larger, thus better compared to the benchmark SPY (10.7%) in the same period.
  • During the last 3 years, the annual performance (CAGR) is 11.7%, which is smaller, thus worse than the value of 13.3% 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.'

Applying this definition to our asset in some examples:
  • Looking at the historical 30 days volatility of 21.1% in the last 5 years of Comcast, we see it is relatively greater, thus worse in comparison to the benchmark SPY (13.4%)
  • During the last 3 years, the historical 30 days volatility is 22%, which is greater, thus worse than the value of 12.3% from the benchmark.

DownVol:

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

Which means for our asset as example:
  • Looking at the downside volatility of 22.4% in the last 5 years of Comcast, we see it is relatively higher, thus worse in comparison to the benchmark SPY (14.6%)
  • Compared with SPY (13.8%) in the period of the last 3 years, the downside risk of 23.2% is greater, 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.'

Using this definition on our asset we see for example:
  • Looking at the ratio of return and volatility (Sharpe) of 0.45 in the last 5 years of Comcast, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.61)
  • Looking at ratio of return and volatility (Sharpe) in of 0.42 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.88).

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.'

Which means for our asset as example:
  • Looking at the downside risk / excess return profile of 0.43 in the last 5 years of Comcast, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.56)
  • During the last 3 years, the excess return divided by the downside deviation is 0.4, which is lower, thus worse than the value of 0.78 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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (3.99 ) in the period of the last 5 years, the Downside risk index of 9.59 of Comcast is larger, thus worse.
  • During the last 3 years, the Downside risk index is 11 , which is higher, thus worse than the value of 4.04 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.'

Using this definition on our asset we see for example:
  • Looking at the maximum reduction from previous high of -28.4 days in the last 5 years of Comcast, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (-19.3 days)
  • During the last 3 years, the maximum drop from peak to valley is -28.4 days, which is lower, thus worse than the value of -19.3 days from the benchmark.

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:
  • Compared with the benchmark SPY (187 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 307 days of Comcast is larger, thus worse.
  • Compared with SPY (139 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 307 days is higher, 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 (41 days) in the period of the last 5 years, the average days under water of 75 days of Comcast is greater, thus worse.
  • Compared with SPY (36 days) in the period of the last 3 years, the average days below previous high of 83 days is larger, thus worse.
