DexCom (DXCM)

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.'

• Looking at the total return of 184.8% in the last 5 years of DexCom, we see it is relatively higher, thus better in comparison to the benchmark SPY (94.2%)
• Compared with SPY (27.9%) in the period of the last 3 years, the total return, or performance of -6.4% is lower, thus worse.

CAGR:

'The compound annual growth rate (CAGR) is a useful measure of growth over multiple time periods. It can be thought of as the growth rate that gets you from the initial investment value to the ending investment value if you assume that the investment has been compounding over the time period.'

• Compared with the benchmark SPY (14.2%) in the period of the last 5 years, the annual return (CAGR) of 23.3% of DexCom is larger, thus better.
• Compared with SPY (8.6%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of -2.2% is lower, thus worse.

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.'

• The volatility over 5 years of DexCom is 47.1%, which is larger, thus worse compared to the benchmark SPY (20.9%) in the same period.
• Compared with SPY (17.3%) in the period of the last 3 years, the volatility of 44.9% is higher, thus worse.

DownVol:

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

• Looking at the downside deviation of 31.2% in the last 5 years of DexCom, we see it is relatively higher, thus worse in comparison to the benchmark SPY (15%)
• Compared with SPY (12.1%) in the period of the last 3 years, the downside volatility of 30.2% 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.'

• Looking at the Sharpe Ratio of 0.44 in the last 5 years of DexCom, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (0.56)
• Looking at risk / return profile (Sharpe) in of -0.1 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.35).

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.'

• The ratio of annual return and downside deviation over 5 years of DexCom is 0.67, which is lower, thus worse compared to the benchmark SPY (0.78) in the same period.
• Looking at downside risk / excess return profile in of -0.15 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.5).

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.'

• The Ulcer Ratio over 5 years of DexCom is 26 , which is larger, thus worse compared to the benchmark SPY (9.32 ) in the same period.
• During the last 3 years, the Ulcer Index is 32 , which is higher, thus worse than the value of 10 from the benchmark.

MaxDD:

'Maximum drawdown is defined as the peak-to-trough decline of an investment during a specific period. It is usually quoted as a percentage of the peak value. The maximum drawdown can be calculated based on absolute returns, in order to identify strategies that suffer less during market downturns, such as low-volatility strategies. However, the maximum drawdown can also be calculated based on returns relative to a benchmark index, for identifying strategies that show steady outperformance over time.'

• The maximum reduction from previous high over 5 years of DexCom is -58.2 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
• Compared with SPY (-24.5 days) in the period of the last 3 years, the maximum DrawDown of -58.2 days is smaller, thus worse.

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). Many assume Max DD Duration is the length of time between new highs during which the Max DD (magnitude) occurred. But that isn’t always the case. The Max DD duration is the longest time between peaks, period. So it could be the time when the program also had its biggest peak to valley loss (and usually is, because the program needs a long time to recover from the largest loss), but it doesn’t have to be'

• Compared with the benchmark SPY (488 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 673 days of DexCom is greater, thus worse.
• Looking at maximum time in days below previous high water mark in of 673 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (488 days).

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 below previous high over 5 years of DexCom is 219 days, which is larger, thus worse compared to the benchmark SPY (123 days) in the same period.
• Looking at average days below previous high in of 308 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (180 days).
