If you own shares in Rockfire Resources plc (LON:ROCK) 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 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 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 ROCK’s beta value tells investors
Zooming in on Rockfire Resources, we see it has a five year beta of 1.20. This is above 1, so historically its share price has been influenced by the broader volatility of the stock market. If this beta value holds true in the future, Rockfire Resources shares are likely to rise more than the market when the market is going up, but fall faster when the market is going down. Beta is worth considering, but it’s also important to consider whether Rockfire Resources is growing earnings and revenue. You can take a look for yourself, below.
Does ROCK’s size influence the expected beta?
Rockfire Resources is a rather small company. It has a market capitalisation of UK£1.7m, which means it is probably under the radar of most investors. Relatively few investors can influence the price of a smaller company, compared to a large company. This could explain the high beta value, in this case.
What this means for you:
Beta only tells us that the Rockfire Resources 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. Ultimately, beta is an interesting metric, but there’s plenty more to learn.
