If you own shares in StoneMor Inc. (NYSE:STON) 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. The first category is company specific volatility. This can be dealt with by limiting your exposure to any particular stock. 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 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. A stock with a beta below one is either less volatile than the market, or more volatile but not corellated with the overall market. In comparison a stock with a beta of over one tends to be move in a similar direction to the market in the long term, but with greater changes in price.
What does STON's beta value mean to investors?
While history does not always repeat, this level of beta may indicate that the stock price will continue to be exposed to market risk, albeit not overly so. 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 StoneMor's revenue and earnings in the image below.
Could STON's size cause it to be more volatile?
StoneMor is a rather small company. It has a market capitalisation of US$127m, which means it is probably under the radar of most investors. Companies this small are usually more volatile than the market, whether or not that volatility is correlated. Therefore, it's a bit surprising to see that this stock has a beta value so close to the overall market.
What this means for you:
It is probable that there is a link between the share price of StoneMor 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.
