Enphase Energy (ENPH)

TotalReturn:

'Total return, when measuring performance, is the actual rate of return of an investment or a pool of investments over a given evaluation period. Total return includes interest, capital gains, dividends and distributions realized over a given period of time. Total return accounts for two categories of return: income including interest paid by fixed-income investments, distributions or dividends and capital appreciation, representing the change in the market price of an asset.'

• Compared with the benchmark SPY (104.2%) in the period of the last 5 years, the total return, or performance of -47.8% of Enphase Energy is lower, thus worse.
• Looking at total return in of -86.4% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (62.9%).

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.'

• Looking at the compounded annual growth rate (CAGR) of -12.2% in the last 5 years of Enphase Energy, we see it is relatively lower, thus worse in comparison to the benchmark SPY (15.4%)
• Looking at annual return (CAGR) in of -48.7% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (17.7%).

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.'

• Compared with the benchmark SPY (17.5%) in the period of the last 5 years, the 30 days standard deviation of 68.1% of Enphase Energy is larger, thus worse.
• Compared with SPY (17.2%) in the period of the last 3 years, the 30 days standard deviation of 65.1% 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.'

• The downside volatility over 5 years of Enphase Energy is 47.9%, which is higher, thus worse compared to the benchmark SPY (12.1%) in the same period.
• Compared with SPY (11.4%) in the period of the last 3 years, the downside risk of 49% is larger, thus worse.

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.'

• The risk / return profile (Sharpe) over 5 years of Enphase Energy is -0.22, which is lower, thus worse compared to the benchmark SPY (0.74) in the same period.
• During the last 3 years, the Sharpe Ratio is -0.79, which is lower, thus worse than the value of 0.89 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.'

• The excess return divided by the downside deviation over 5 years of Enphase Energy is -0.31, which is lower, thus worse compared to the benchmark SPY (1.07) in the same period.
• Compared with SPY (1.33) in the period of the last 3 years, the excess return divided by the downside deviation of -1.04 is smaller, thus worse.

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 (8.48 ) in the period of the last 5 years, the Downside risk index of 52 of Enphase Energy is greater, thus worse.
• Compared with SPY (4.62 ) in the period of the last 3 years, the Ulcer Index of 64 is greater, 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.'

• Compared with the benchmark SPY (-24.5 days) in the period of the last 5 years, the maximum DrawDown of -91 days of Enphase Energy is smaller, thus worse.
• During the last 3 years, the maximum DrawDown is -91 days, which is smaller, thus worse than the value of -18.8 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.'

• The maximum days under water over 5 years of Enphase Energy is 681 days, which is higher, thus worse compared to the benchmark SPY (488 days) in the same period.
• Compared with SPY (109 days) in the period of the last 3 years, the maximum days under water of 681 days is larger, 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 (120 days) in the period of the last 5 years, the average days below previous high of 225 days of Enphase Energy is higher, thus worse.
• Looking at average days below previous high in of 313 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (28 days).
