Fortinet (FTNT)

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 (95%) in the period of the last 5 years, the total return, or performance of 233.9% of Fortinet is higher, thus better.
• During the last 3 years, the total return is 4.6%, which is smaller, thus worse than the value of 29% 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.'

• Looking at the annual performance (CAGR) of 27.3% in the last 5 years of Fortinet, we see it is relatively greater, thus better in comparison to the benchmark SPY (14.3%)
• Looking at compounded annual growth rate (CAGR) in of 1.5% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (8.9%).

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.'

• Looking at the volatility of 44.4% in the last 5 years of Fortinet, we see it is relatively larger, thus worse in comparison to the benchmark SPY (20.9%)
• During the last 3 years, the 30 days standard deviation is 44%, which is greater, thus worse than the value of 17.3% from the benchmark.

DownVol:

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

• The downside volatility over 5 years of Fortinet is 31.9%, which is larger, thus worse compared to the benchmark SPY (15%) in the same period.
• Looking at downside risk in of 33.7% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (12.1%).

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.'

• Looking at the risk / return profile (Sharpe) of 0.56 in the last 5 years of Fortinet, we see it is relatively larger, thus better in comparison to the benchmark SPY (0.56)
• During the last 3 years, the ratio of return and volatility (Sharpe) is -0.02, which is lower, thus worse than the value of 0.37 from the benchmark.

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.'

• Compared with the benchmark SPY (0.79) in the period of the last 5 years, the excess return divided by the downside deviation of 0.78 of Fortinet is lower, thus worse.
• Compared with SPY (0.53) in the period of the last 3 years, the ratio of annual return and downside deviation of -0.03 is lower, thus worse.

Ulcer:

'Ulcer Index is a method for measuring investment risk that addresses the real concerns of investors, unlike the widely used standard deviation of return. UI is a measure of the depth and duration of drawdowns in prices from earlier highs. Using Ulcer Index instead of standard deviation can lead to very different conclusions about investment risk and risk-adjusted return, especially when evaluating strategies that seek to avoid major declines in portfolio value (market timing, dynamic asset allocation, hedge funds, etc.). The Ulcer Index was originally developed in 1987. Since then, it has been widely recognized and adopted by the investment community. According to Nelson Freeburg, editor of Formula Research, Ulcer Index is “perhaps the most fully realized statistical portrait of risk there is.'

• The Ulcer Ratio over 5 years of Fortinet is 18 , which is larger, thus worse compared to the benchmark SPY (9.32 ) in the same period.
• Compared with SPY (10 ) in the period of the last 3 years, the Ulcer Index of 21 is higher, thus worse.

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.'

• Looking at the maximum DrawDown of -38.3 days in the last 5 years of Fortinet, we see it is relatively lower, thus worse in comparison to the benchmark SPY (-33.7 days)
• During the last 3 years, the maximum drop from peak to valley is -38.3 days, which is lower, thus worse than the value of -24.5 days from the benchmark.

MaxDuration:

'The Maximum 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. It is the length of time the account was in the Max Drawdown. A Max Drawdown measures a retrenchment from when an equity curve reaches a new high. It’s the maximum an account lost during that retrenchment. This method is applied because a valley can’t be measured until a new high occurs. Once the new high is reached, the percentage change from the old high to the bottom of the largest trough is recorded.'

• Compared with the benchmark SPY (488 days) in the period of the last 5 years, the maximum days under water of 368 days of Fortinet is smaller, thus better.
• During the last 3 years, the maximum time in days below previous high water mark is 368 days, which is lower, thus better than the value of 488 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 under water over 5 years of Fortinet is 101 days, which is lower, thus better compared to the benchmark SPY (123 days) in the same period.
• Compared with SPY (179 days) in the period of the last 3 years, the average time in days below previous high water mark of 141 days is smaller, thus better.
