Zscaler (ZS)

TotalReturn:

'Total return is the amount of value an investor earns from a security over a specific period, typically one year, when all distributions are reinvested. Total return is expressed as a percentage of the amount invested. For example, a total return of 20% means the security increased by 20% of its original value due to a price increase, distribution of dividends (if a stock), coupons (if a bond) or capital gains (if a fund). Total return is a strong measure of an investment’s overall performance.'

• The total return over 5 years of Zscaler is 181.1%, which is greater, thus better compared to the benchmark SPY (108.3%) in the same period.
• Compared with SPY (49.1%) in the period of the last 3 years, the total return, or increase in value of 80.1% is higher, thus better.

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 23% in the last 5 years of Zscaler, we see it is relatively larger, thus better in comparison to the benchmark SPY (15.8%)
• Looking at annual return (CAGR) in of 21.8% in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (14.3%).

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 55.6% in the last 5 years of Zscaler, we see it is relatively higher, thus worse in comparison to the benchmark SPY (17.9%)
• Compared with SPY (18.1%) in the period of the last 3 years, the volatility of 52.9% is higher, thus worse.

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 Zscaler is 38%, which is higher, thus worse compared to the benchmark SPY (12.4%) in the same period.
• Looking at downside deviation in of 36% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (12.2%).

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.'

• The ratio of return and volatility (Sharpe) over 5 years of Zscaler is 0.37, which is smaller, thus worse compared to the benchmark SPY (0.75) in the same period.
• Looking at ratio of return and volatility (Sharpe) in of 0.36 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.65).

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.'

• Compared with the benchmark SPY (1.07) in the period of the last 5 years, the ratio of annual return and downside deviation of 0.54 of Zscaler is lower, thus worse.
• During the last 3 years, the excess return divided by the downside deviation is 0.54, which is lower, thus worse than the value of 0.97 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 Ratio of 44 in the last 5 years of Zscaler, we see it is relatively higher, thus worse in comparison to the benchmark SPY (8.49 )
• Looking at Ulcer Index in of 26 in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (5.55 ).

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 DrawDown over 5 years of Zscaler is -76.4 days, which is smaller, thus worse compared to the benchmark SPY (-24.5 days) in the same period.
• Looking at maximum reduction from previous high in of -55.1 days in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (-18.8 days).

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.'

• The maximum days under water over 5 years of Zscaler is 883 days, which is higher, thus worse compared to the benchmark SPY (488 days) in the same period.
• Compared with SPY (199 days) in the period of the last 3 years, the maximum days below previous high of 322 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.'

• Looking at the average time in days below previous high water mark of 334 days in the last 5 years of Zscaler, we see it is relatively higher, thus worse in comparison to the benchmark SPY (119 days)
• Compared with SPY (46 days) in the period of the last 3 years, the average time in days below previous high water mark of 138 days is higher, thus worse.
