Intuitive Surgical (ISRG)

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, or increase in value over 5 years of Intuitive Surgical is 92.4%, which is greater, thus better compared to the benchmark SPY (74.4%) in the same period.
• Compared with SPY (69.4%) in the period of the last 3 years, the total return, or increase in value of 82.7% is greater, thus better.

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.'

• Compared with the benchmark SPY (11.8%) in the period of the last 5 years, the annual return (CAGR) of 14% of Intuitive Surgical is greater, thus better.
• Looking at annual performance (CAGR) in of 22.4% in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (19.3%).

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.'

• Looking at the volatility of 33% in the last 5 years of Intuitive Surgical, we see it is relatively higher, thus worse in comparison to the benchmark SPY (17%)
• Looking at 30 days standard deviation in of 30.3% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (15%).

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.'

• The downside deviation over 5 years of Intuitive Surgical is 22.1%, which is greater, thus worse compared to the benchmark SPY (11.8%) in the same period.
• Compared with SPY (10.1%) in the period of the last 3 years, the downside risk of 19% is greater, thus worse.

Sharpe:

'The Sharpe ratio (also known as the Sharpe index, the Sharpe measure, and the reward-to-variability ratio) is a way to examine the performance of an investment by adjusting for its risk. The ratio measures the excess return (or risk premium) per unit of deviation in an investment asset or a trading strategy, typically referred to as risk, named after William F. Sharpe.'

• The Sharpe Ratio over 5 years of Intuitive Surgical is 0.35, which is lower, thus worse compared to the benchmark SPY (0.55) in the same period.
• Looking at ratio of return and volatility (Sharpe) in of 0.66 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (1.12).

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.'

• Looking at the ratio of annual return and downside deviation of 0.52 in the last 5 years of Intuitive Surgical, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.79)
• Looking at ratio of annual return and downside deviation in of 1.05 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (1.66).

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 (8.43 ) in the period of the last 5 years, the Downside risk index of 20 of Intuitive Surgical is higher, thus worse.
• Looking at Ulcer Index in of 12 in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (3.44 ).

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 (-24.5 days) in the period of the last 5 years, the maximum DrawDown of -49.9 days of Intuitive Surgical is lower, thus worse.
• Compared with SPY (-18.8 days) in the period of the last 3 years, the maximum DrawDown of -29.6 days is smaller, thus worse.

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 549 days of Intuitive Surgical is higher, thus worse.
• During the last 3 years, the maximum time in days below previous high water mark is 295 days, which is higher, thus worse than the value of 87 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.'

• Compared with the benchmark SPY (119 days) in the period of the last 5 years, the average time in days below previous high water mark of 171 days of Intuitive Surgical is greater, thus worse.
• Looking at average days under water in of 80 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (20 days).
