If you own shares in Gränges AB (publ) (STO:GRNG) then it’s worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. 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 sort is caused by the natural volatility of markets, overall. For example, certain macroeconomic events will impact (virtually) all stocks on the market.
Some stocks see their prices move in concert with the market. Others tend towards stronger, gentler or unrelated 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 GRNG’s beta value
Given that it has a beta of 0.88, we can surmise that the Gränges 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 0.88. 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 Gränges’s revenue and earnings in the image below.
Could GRNG’s size cause it to be more volatile?
Gränges is a small cap stock with a market capitalisation of kr6.6b. Most companies this size are actively traded. Small cap stocks ofthen have a higher beta than the overall market. However, small companies can also be strongly impacted by company specific developments, which can move the share price in ways that are unrelated to the broader market. That could explain why this one has a low beta value.
What this means for you:
Since Gränges 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 GRNG is a good investment for you, we also need to consider important company-specific fundamentals such as Gränges’s financial health and performance track record.
