Anyone researching Renishaw plc (LON:RSW) might want to consider the historical volatility of the share price. Modern finance theory considers volatility to be a measure of risk, and there are two main types of price volatility. The first type is company specific volatility. Investors use diversification across uncorrelated stocks to reduce this kind of price volatility across the 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 see their prices move in concert with the market. Others tend towards stronger, gentler or unrelated price movements. Beta is a widely used metric to measure a stock's exposure to market risk (volatility). Before we go on, it's worth noting that Warren Buffett pointed out in his 2014 letter to shareholders that 'volatility is far from synonymous with risk.' Having said that, beta can still be rather useful. The first thing to understand about beta is 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 we can learn from RSW's beta value

Given that it has a beta of 0.84, we can surmise that the Renishaw share price has not been strongly impacted by broader market volatility (over the last 5 years). If history is a good guide, owning the stock should help ensure that your portfolio is not overly sensitive to market volatility. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall.

Could RSW's size cause it to be more volatile?

Renishaw is a fairly large company. It has a market capitalisation of UK£3.0b, which means it is probably on the radar of most investors. When a large company like this trades with a low beta value, it is often because there is some other systemic factor influencing the share price. For example, commodity prices might influence a mining company strongly, while expectations around dividend payments (and capital expenditure requirements) might have a big impact on utilities.

What this means for you:

Since Renishaw 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. This article aims to educate investors about beta values, but it's well worth looking at important company-specific fundamentals such as Renishaw’s financial health and performance track record.
