Anyone researching GHP Specialty Care AB (publ) (STO:GHP) 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 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. 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 does GHP's beta value mean to investors?
Looking at the last five years, GHP Specialty Care has a beta of 0.81. The fact that this is well below 1 indicates that its share price movements haven't historically been very sensitive to overall market volatility. This means that -- if history is a guide -- buying the stock would reduce the impact of overall market volatility in many portfolios (depending on the beta of the portfolio, of course). Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall.

Does GHP's size influence the expected beta?
With a market capitalisation of kr1.0b, GHP Specialty Care 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:
The GHP Specialty Care 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. In order to fully understand whether GHP is a good investment for you, we also need to consider important company-specific fundamentals such as GHP Specialty Care’s financial health and performance track record.
