If you own shares in Cabot Energy Plc (LON:CAB) then it’s worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. 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 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 CAB’s beta value tells investors
Zooming in on Cabot Energy, we see it has a five year beta of 1.10. This is above 1, so historically its share price has been influenced by the broader volatility of the stock market. If the past is any guide, we would expect that Cabot Energy 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 Cabot Energy’s revenue and earnings in the image below.
How does CAB’s size impact its beta?
Cabot Energy is a noticeably small company, with a market capitalisation of UK£1.7m. Most companies this size are not always actively traded. 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:
Beta only tells us that the Cabot Energy share price is sensitive to broader market movements. This could indicate that it is a high growth company, or is heavily influenced by sentiment because it is speculative. Alternatively, it could have operating leverage in its business model.
