Anyone researching Groupe Guillin S.A. (EPA:ALGIL) 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. The first category is company specific volatility. This can be dealt with by limiting your exposure to any particular stock. 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. Beta can be a useful tool to understand how much a stock is influenced by market risk (volatility). However, Warren Buffett said ‘volatility is far from synonymous with risk’ in his 2014 letter to investors. So, while useful, beta is not the only metric to consider. To use beta as an investor, you must first understand that the overall market has a beta of 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 does ALGIL’s beta value mean to investors?
Zooming in on Groupe Guillin, we see it has a five year beta of 0.83. This is below 1, so historically its share price has been rather independent from the market. This suggests that including it in your portfolio will reduce volatility arising from broader market movements, assuming your portfolio’s weighted average beta is higher than 0.83. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall.

How does ALGIL’s size impact its beta?
With a market capitalisation of €323m, Groupe Guillin is a very small company by global standards. It is quite likely to be unknown to most investors. Companies with market capitalisations around this size often show poor correlation with the broader market because market volatility is overshadowed by company specific events, or other factors. It’s worth checking to see how often shares are traded, because very small companies with very low beta values are often only thinly traded.
What this means for you:
The Groupe Guillin doesn’t usually show much sensitivity to the broader market. This could be for a variety of reasons. Typically, smaller companies have a low beta if their share price tends to move a lot due to company specific developments. Alternatively, an strong dividend payer might move less than the market because investors are valuing it for its income stream.
