If you're interested in Enphase Energy, Inc. (NASDAQ:ENPH), then you might want to consider its beta (a measure of share price volatility) in order to understand how the stock could impact your portfolio. Modern finance theory considers volatility to be a measure of risk, and there are two main types of price volatility. First, we have company specific volatility, which is the price gyrations of an individual stock. Holding at least 8 stocks can reduce this kind of risk across a portfolio. The second type is the broader market volatility, which you cannot diversify away, since it arises from macroeconomic factors which directly affects all the stocks on the market.
Some stocks mimic the volatility of the market quite closely, while others demonstrate muted, exagerrated or uncorrelated price movements. Some investors use beta as a measure of how much a certain stock is impacted by market risk (volatility). While we should keep in mind that Warren Buffett has cautioned that 'Volatility is far from synonymous with risk', beta is still a useful factor to consider. To make good use of it you must first know that the beta of the overall market is one. Any stock with a beta of greater than one is considered more volatile than the market, while those with a beta below one are either less volatile or poorly correlated with the market.
What does ENPH's beta value mean to investors?
As it happens, Enphase Energy has a five year beta of 0.98. This is fairly close to 1, so the stock has historically shown a somewhat similar level of volatility as the market. Using history as a guide, we might surmise that the share price is likely to be influenced by market voltility going forward but it probably won't be particularly sensitive to it. Beta is worth considering, but it's also important to consider whether Enphase Energy is growing earnings and revenue. You can take a look for yourself, below.
Could ENPH's size cause it to be more volatile?
With a market capitalisation of US$3.1b, Enphase Energy is a pretty big company, even by global standards. It is quite likely well known to very many investors. It's not overly surprising to see large companies with beta values reasonably close to the market average. After all, large companies make up a higher weighting of the index than do small companies.
What this means for you:
Since Enphase Energy has a beta close to one, it will probably show a positive return when the market is moving up, based on history. If you're trying to generate better returns than the market, it would be worth thinking about other metrics such as cashflows, dividends and revenue growth might be a more useful guide to the future.
