Anyone researching Systemair AB (publ) (STO:SYSR) might want to consider the historical volatility of the share price. Volatility is considered to be a measure of risk in modern finance theory. Investors may think of volatility as falling into two main categories. The first type is company specific volatility. Investors use diversification across uncorrelated stocks to reduce this kind of price volatility across the 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 SYSR's beta value
With a beta of 0.92, (which is quite close to 1) the share price of Systemair has historically been about as voltile as the broader market. Using history as a guide, we might surmise that the share price is likely to be influenced by market voltility going forward but it probably won't be particularly sensitive to it. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall. You can see Systemair's revenue and earnings in the image below.
Could SYSR's size cause it to be more volatile?
With a market capitalisation of kr6.5b, Systemair is a small cap stock. However, it is big enough to catch the attention of professional investors. Small companies often have a high beta value because the stock price can move on relatively low capital flows. So it's interesting to note that this stock historically has a beta value quite close to one.
What this means for you:
It is probable that there is a link between the share price of Systemair and the broader market, since it has a beta value quite close to one. However, long term investors are generally well served by looking past market volatility and focussing on the underlying development of the business. If that's your game, metrics such as revenue, earnings and cash flow will be more useful. This article aims to educate investors about beta values, but it's well worth looking at important company-specific fundamentals such as Systemair’s financial health and performance track record.
