If you own shares in EnerSys (NYSE:ENS) then it's worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. Modern finance theory considers volatility to be a measure of risk, and there are two main types of price volatility. The first category is company specific volatility. This can be dealt with by limiting your exposure to any particular stock. The other type, which cannot be diversified away, is the volatility of the entire market. Every stock in the market is exposed to this volatility, which is linked to the fact that stocks prices are correlated in an efficient market.

Some stocks see their prices move in concert with the market. Others tend towards stronger, gentler or unrelated 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 greater than one is more sensitive to broader market movements than a stock with a beta of less than one.

What we can learn from ENS's beta value

Given that it has a beta of 1.54, we can surmise that the EnerSys share price has been fairly sensitive to market volatility (over the last 5 years). If the past is any guide, we would expect that EnerSys shares will rise quicker than the markets in times of optimism, but fall faster in times of pessimism. Share price volatility is well worth considering, but most long term investors consider the history of revenue and earnings growth to be more important. Take a look at how EnerSys fares in that regard, below.

NYSE:ENS Income Statement, July 11th 2019

How does ENS's size impact its beta?

EnerSys is a reasonably big company, with a market capitalisation of US$2.8b. Most companies this size are actively traded with decent volumes of shares changing hands each day. It takes deep pocketed investors to influence the share price of a large company, so it's a little unusual to see companies this size with high beta values. It may be that that this company is more heavily impacted by broader economic factors than most.

What this means for you:

Since EnerSys has a reasonably high beta, it's worth considering why it is so heavily influenced by broader market sentiment. For example, it might be a high growth stock or have a lot of operating leverage in its business model. In order to fully understand whether ENS is a good investment for you, we also need to consider important company-specific fundamentals such as EnerSys’s financial health and performance track record.
