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 (81.5%) in the period of the last 5 years, the total return, or increase in value of 611% of Fortinet is greater, thus better.
• During the last 3 years, the total return is 212.4%, which is greater, thus better than the value of 48.1% from the benchmark.

CAGR:

'Compound annual growth rate (CAGR) is a business and investing specific term for the geometric progression ratio that provides a constant rate of return over the time period. CAGR is not an accounting term, but it is often used to describe some element of the business, for example revenue, units delivered, registered users, etc. CAGR dampens the effect of volatility of periodic returns that can render arithmetic means irrelevant. It is particularly useful to compare growth rates from various data sets of common domain such as revenue growth of companies in the same industry.'

• Looking at the annual performance (CAGR) of 48.1% in the last 5 years of Fortinet, we see it is relatively greater, thus better in comparison to the benchmark SPY (12.7%)
• Looking at compounded annual growth rate (CAGR) in of 46.3% in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (14%).

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 (20.5%) in the period of the last 5 years, the volatility of 42.2% of Fortinet is larger, thus worse.
• Compared with SPY (23.8%) in the period of the last 3 years, the historical 30 days volatility of 47.3% is higher, thus worse.

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.'

• Compared with the benchmark SPY (15%) in the period of the last 5 years, the downside deviation of 29.2% of Fortinet is greater, thus worse.
• During the last 3 years, the downside volatility is 32.7%, which is higher, thus worse than the value of 17.3% 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.'

• Looking at the risk / return profile (Sharpe) of 1.08 in the last 5 years of Fortinet, we see it is relatively larger, thus better in comparison to the benchmark SPY (0.5)
• Looking at risk / return profile (Sharpe) in of 0.92 in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (0.48).

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 (0.68) in the period of the last 5 years, the ratio of annual return and downside deviation of 1.56 of Fortinet is higher, thus better.
• Looking at excess return divided by the downside deviation in of 1.34 in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (0.66).

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 12 in the last 5 years of Fortinet, we see it is relatively higher, thus worse in comparison to the benchmark SPY (7.13 )
• Looking at Downside risk index in of 12 in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (8.25 ).

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.'

• The maximum drop from peak to valley over 5 years of Fortinet is -37.6 days, which is smaller, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
• Looking at maximum drop from peak to valley in of -37.6 days in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (-33.7 days).

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 (150 days) in the period of the last 5 years, the maximum days below previous high of 155 days of Fortinet is higher, thus worse.
• Compared with SPY (150 days) in the period of the last 3 years, the maximum days under water of 155 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.'

• Compared with the benchmark SPY (41 days) in the period of the last 5 years, the average days below previous high of 41 days of Fortinet is larger, thus worse.
• Compared with SPY (36 days) in the period of the last 3 years, the average time in days below previous high water mark of 38 days is larger, thus worse.
