If you’re interested in Grainger plc (LON:GRI), 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. 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 type is company specific volatility. Investors use diversification across uncorrelated stocks to reduce this kind of price volatility across the 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. 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 GRI’s beta value tells investors
Zooming in on Grainger, we see it has a five year beta of 0.85. This is below 1, so historically its share price has been rather independent from the market. 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. You can see Grainger’s revenue and earnings in the image below.
Does GRI’s size influence the expected beta?
Grainger is a small cap stock with a market capitalisation of UK£1.3b. Most companies this size are actively traded. Small cap stocks ofthen have a higher beta than the overall market. However, small companies can also be strongly impacted by company specific developments, which can move the share price in ways that are unrelated to the broader market. That could explain why this one has a low beta value.
What this means for you:
Since Grainger is not heavily influenced by market moves, its share price is probably far more dependend on company specific developments. It could pay to take a closer look at metrics such as revenue growth, earnings growth, and debt.
