If you're interested in Enertime SA (EPA:ALENE), 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. Volatility is considered to be a measure of risk in modern finance theory. Investors may think of volatility as falling into two main categories. 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 sort is caused by the natural volatility of markets, overall. For example, certain macroeconomic events will impact (virtually) all 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. A stock with a beta below one is either less volatile than the market, or more volatile but not corellated with the overall market. In comparison a stock with a beta of over one tends to be move in a similar direction to the market in the long term, but with greater changes in price.

What we can learn from ALENE's beta value
Enertime has a five-year beta of 0.96. This is reasonably close to the market beta of 1, so the stock has in the past displayed similar levels of volatility to the overall market. If the future looks like the past, we could therefore consider it likely that the stock price will experience share price volatility that is roughly similar to the overall market. Beta is worth considering, but it's also important to consider whether Enertime is growing earnings and revenue. You can take a look for yourself, below.
Does ALENE's size influence the expected beta?
Enertime is a rather small company. It has a market capitalisation of €3.8m, which means it is probably under the radar of most investors. Companies this small are usually more volatile than the market, whether or not that volatility is correlated. Therefore, it's a bit surprising to see that this stock has a beta value so close to the overall market.
What this means for you:
Enertime has a beta value quite close to that of the overall market. That doesn't tell us much on its own, so it is probably worth considering whether the company is growing, if you're looking for stocks that will go up more than the overall market. In order to fully understand whether ALENE is a good investment for you, we also need to consider important company-specific fundamentals such as Enertime’s financial health and performance track record.
