Netflix (NFLX)

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.'

• The total return over 5 years of Netflix is 369.6%, which is higher, thus better compared to the benchmark SPY (67.9%) in the same period.
• Looking at total return, or increase in value in of 154% in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (38.6%).

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.'

• Compared with the benchmark SPY (10.9%) in the period of the last 5 years, the annual return (CAGR) of 36.3% of Netflix is higher, thus better.
• Compared with SPY (11.5%) in the period of the last 3 years, the annual performance (CAGR) of 36.4% is larger, thus better.

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.'

• The historical 30 days volatility over 5 years of Netflix is 41.9%, which is higher, thus worse compared to the benchmark SPY (18.7%) in the same period.
• During the last 3 years, the historical 30 days volatility is 40.7%, which is higher, thus worse than the value of 21.5% 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.'

• Looking at the downside deviation of 27.5% in the last 5 years of Netflix, we see it is relatively greater, thus worse in comparison to the benchmark SPY (13.6%)
• During the last 3 years, the downside volatility is 27.1%, which is higher, thus worse than the value of 15.7% from the benchmark.

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.'

• Compared with the benchmark SPY (0.45) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of 0.81 of Netflix is larger, thus better.
• Compared with SPY (0.42) in the period of the last 3 years, the Sharpe Ratio of 0.83 is larger, thus better.

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.'

• The excess return divided by the downside deviation over 5 years of Netflix is 1.23, which is greater, thus better compared to the benchmark SPY (0.62) in the same period.
• During the last 3 years, the ratio of annual return and downside deviation is 1.25, which is larger, thus better than the value of 0.57 from the benchmark.

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.'

• Looking at the Ulcer Index of 18 in the last 5 years of Netflix, we see it is relatively larger, thus worse in comparison to the benchmark SPY (5.82 )
• During the last 3 years, the Downside risk index is 17 , which is greater, thus worse than the value of 6.87 from the benchmark.

MaxDD:

'Maximum drawdown measures the loss in any losing period during a fund’s investment record. It is defined as the percent retrenchment from a fund’s peak value to the fund’s valley value. The drawdown is in effect from the time the fund’s retrenchment begins until a new fund high is reached. The maximum drawdown encompasses both the period from the fund’s peak to the fund’s valley (length), and the time from the fund’s valley to a new fund high (recovery). It measures the largest percentage drawdown that has occurred in any fund’s data record.'

• The maximum drop from peak to valley over 5 years of Netflix is -44.2 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
• During the last 3 years, the maximum reduction from previous high is -44.2 days, which is lower, thus worse than the value of -33.7 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.'

• Looking at the maximum time in days below previous high water mark of 444 days in the last 5 years of Netflix, we see it is relatively greater, thus worse in comparison to the benchmark SPY (187 days)
• Looking at maximum days under water in of 444 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 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.'

• Compared with the benchmark SPY (43 days) in the period of the last 5 years, the average time in days below previous high water mark of 123 days of Netflix is higher, thus worse.
• During the last 3 years, the average days under water is 145 days, which is greater, thus worse than the value of 39 days from the benchmark.
