If you're interested in Cognor Holding S.A. (WSE:COG), 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. 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 other type, which cannot be diversified away, is the volatility of the entire market. Every stock in the market is exposed to this volatility, which is linked to the fact that stocks prices are correlated in an efficient market.
Some stocks are more sensitive to general market forces than others. 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 does COG's beta value mean to investors?
Given that it has a beta of 1.22, we can surmise that the Cognor Holding share price has been fairly sensitive to market volatility (over the last 5 years). If the past is any guide, we would expect that Cognor Holding shares will rise quicker than the markets in times of optimism, but fall faster in times of pessimism. 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 Cognor Holding's revenue and earnings in the image below.
Does COG's size influence the expected beta?
With a market capitalisation of zł193m, Cognor Holding is a very small company by global standards. It is quite likely to be unknown to most investors. It takes less money to influence the share price of a very small company. This may explain the excess volatility implied by this beta value.
What this means for you:
Since Cognor Holding has a reasonably high beta, it's worth considering why it is so heavily influenced by broader market sentiment. For example, it might be a high growth stock or have a lot of operating leverage in its business model.
