Anyone researching Ardagh Group S.A. (NYSE:ARD) might want to consider the historical volatility of the share price. 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 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 ARD's beta value
Given that it has a beta of 1.23, we can surmise that the Ardagh Group share price has been fairly sensitive to market volatility (over the last 5 years). If this beta value holds true in the future, Ardagh Group shares are likely to rise more than the market when the market is going up, but fall faster when the market is going down. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall.

With a market capitalisation of US$4.6b, Ardagh Group is a pretty big company, even by global standards. It is quite likely well known to very many investors. It has a relatively high beta, suggesting it may be somehow leveraged to macroeconomic conditions. For example, it might be a high growth stock with lots of investors trading the shares. It's notable when large companies to have high beta values, because it usually takes substantial capital flows to move their share prices.
What this means for you:
