Does The Groupe Guillin S.A. (EPA:ALGIL) Share Price Tend To Follow The Market?

Simply Wall St

If you're interested in Groupe Guillin S.A. (EPA:ALGIL), 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 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. 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 we can learn from ALGIL's beta value

Given that it has a beta of 0.83, we can surmise that the Groupe Guillin share price has not been strongly impacted by broader market volatility (over the last 5 years). 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. 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 Groupe Guillin fares in that regard, below.

Could ALGIL's size cause it to be more volatile?

With a market capitalisation of €345m, Groupe Guillin is a very small company by global standards. It is quite likely to be unknown to most investors. It is not unusual for very small companies to have a low beta value, especially if only low volumes of shares are traded. Even when they are traded more actively, the share price is often more susceptible to company specific developments than overall market volatility.

What this means for you:

Since Groupe Guillin is not heavily influenced by market moves, its share price is probably far more dependend on company specific developments. It could pay to take a closer look at metrics such as revenue growth, earnings growth, and debt. In order to fully understand whether ALGIL is a good investment for you, we also need to consider important company-specific fundamentals such as Groupe Guillin’s financial health and performance track record.
