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 (68.1%) in the period of the last 5 years, the total return, or increase in value of 39.2% of Comcast is lower, thus worse.
• Compared with SPY (47%) in the period of the last 3 years, the total return, or performance of 7.2% is lower, thus worse.

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.'

• Looking at the annual return (CAGR) of 6.8% in the last 5 years of Comcast, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (11%)
• Compared with SPY (13.7%) in the period of the last 3 years, the annual return (CAGR) of 2.3% is lower, thus worse.

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.'

• Compared with the benchmark SPY (21.4%) in the period of the last 5 years, the 30 days standard deviation of 28.4% of Comcast is greater, thus worse.
• Compared with SPY (18.7%) in the period of the last 3 years, the volatility of 26.8% is greater, thus worse.

DownVol:

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

• The downside deviation over 5 years of Comcast is 19.9%, which is greater, thus worse compared to the benchmark SPY (15.4%) in the same period.
• Looking at downside deviation in of 19.3% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (13.3%).

Sharpe:

'The Sharpe ratio was developed by Nobel laureate William F. Sharpe, and is used to help investors understand the return of an investment compared to its risk. The ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk. Subtracting the risk-free rate from the mean return allows an investor to better isolate the profits associated with risk-taking activities. One intuition of this calculation is that a portfolio engaging in 'zero risk' investments, such as the purchase of U.S. Treasury bills (for which the expected return is the risk-free rate), has a Sharpe ratio of exactly zero. Generally, the greater the value of the Sharpe ratio, the more attractive the risk-adjusted return.'

• The ratio of return and volatility (Sharpe) over 5 years of Comcast is 0.15, which is lower, thus worse compared to the benchmark SPY (0.4) 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 smaller, thus worse in comparison to SPY (0.6).

Sortino:

'The Sortino ratio improves upon the Sharpe ratio by isolating downside volatility from total volatility by dividing excess return by the downside deviation. The Sortino ratio is a variation of the Sharpe ratio that differentiates harmful volatility from total overall volatility by using the asset's standard deviation of negative asset returns, called downside deviation. The Sortino ratio takes the asset's return and subtracts the risk-free rate, and then divides that amount by the asset's downside deviation. The ratio was named after Frank A. Sortino.'

• Looking at the ratio of annual return and downside deviation of 0.22 in the last 5 years of Comcast, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.55)
• Compared with SPY (0.84) in the period of the last 3 years, the excess return divided by the downside deviation of -0.01 is lower, thus worse.

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.'

• Compared with the benchmark SPY (9.45 ) in the period of the last 5 years, the Downside risk index of 20 of Comcast is greater, thus worse.
• During the last 3 years, the Downside risk index is 25 , which is greater, thus worse than the value of 10 from the benchmark.

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.'

• Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum drop from peak to valley of -52.1 days of Comcast is smaller, thus worse.
• During the last 3 years, the maximum drop from peak to valley is -52.1 days, which is smaller, thus worse than the value of -24.5 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). Many assume Max DD Duration is the length of time between new highs during which the Max DD (magnitude) occurred. But that isn’t always the case. The Max DD duration is the longest time between peaks, period. So it could be the time when the program also had its biggest peak to valley loss (and usually is, because the program needs a long time to recover from the largest loss), but it doesn’t have to be'

• Compared with the benchmark SPY (351 days) in the period of the last 5 years, the maximum days below previous high of 435 days of Comcast is higher, thus worse.
• During the last 3 years, the maximum days below previous high is 435 days, which is larger, thus worse than the value of 351 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.'

• The average days below previous high over 5 years of Comcast is 108 days, which is higher, thus worse compared to the benchmark SPY (78 days) in the same period.
• Compared with SPY (101 days) in the period of the last 3 years, the average days under water of 140 days is higher, thus worse.
