Comcast (CMCSA)

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.'

• Compared with the benchmark SPY (63%) in the period of the last 5 years, the total return, or increase in value of 8.7% of Comcast is smaller, thus worse.
• Compared with SPY (33.5%) in the period of the last 3 years, the total return, or increase in value of 0.4% is smaller, 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.'

• The annual performance (CAGR) over 5 years of Comcast is 1.7%, which is lower, thus worse compared to the benchmark SPY (10.3%) in the same period.
• During the last 3 years, the compounded annual growth rate (CAGR) is 0.1%, which is smaller, thus worse than the value of 10.1% from the benchmark.

Volatility:

'Volatility is a statistical measure of the dispersion of returns for a given security or market index. Volatility can either be measured by using the standard deviation or variance between returns from that same security or market index. Commonly, the higher the volatility, the riskier the security. In the securities markets, volatility is often associated with big swings in either direction. For example, when the stock market rises and falls more than one percent over a sustained period of time, it is called a 'volatile' market.'

• The volatility over 5 years of Comcast is 28.7%, which is higher, thus worse compared to the benchmark SPY (21.6%) in the same period.
• Looking at volatility in of 31.4% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (25.1%).

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.'

• Compared with the benchmark SPY (15.6%) in the period of the last 5 years, the downside risk of 20.6% of Comcast is greater, thus worse.
• Compared with SPY (18.1%) in the period of the last 3 years, the downside deviation of 22.6% is larger, 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.'

• Compared with the benchmark SPY (0.36) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of -0.03 of Comcast is lower, thus worse.
• Looking at risk / return profile (Sharpe) in of -0.08 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.3).

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.'

• Looking at the downside risk / excess return profile of -0.04 in the last 5 years of Comcast, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.5)
• Compared with SPY (0.42) in the period of the last 3 years, the excess return divided by the downside deviation of -0.1 is lower, thus worse.

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.'

• Compared with the benchmark SPY (8.88 ) in the period of the last 5 years, the Ulcer Ratio of 19 of Comcast is larger, thus worse.
• Looking at Ulcer Index in of 23 in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (11 ).

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.'

• The maximum drop from peak to valley over 5 years of Comcast is -52.1 days, which is smaller, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
• Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum drop from peak to valley of -52.1 days is smaller, thus worse.

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.'

• Looking at the maximum days under water of 357 days in the last 5 years of Comcast, we see it is relatively greater, thus worse in comparison to the benchmark SPY (273 days)
• Looking at maximum days below previous high in of 357 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (273 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.'

• Compared with the benchmark SPY (57 days) in the period of the last 5 years, the average days below previous high of 109 days of Comcast is greater, thus worse.
• During the last 3 years, the average days below previous high is 109 days, which is larger, thus worse than the value of 73 days from the benchmark.
