If you own shares in Storebrand ASA (OB:STB) 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 sort is caused by the natural volatility of markets, overall. For example, certain macroeconomic events will impact (virtually) all stocks on the market.
Some stocks see their prices move in concert with the market. Others tend towards stronger, gentler or unrelated 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 we can learn from STB's beta value
Given that it has a beta of 0.83, we can surmise that the Storebrand share price has not been strongly impacted by broader market volatility (over the last 5 years). 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). Share price volatility is well worth considering, but most long term investors consider the history of revenue and earnings growth to be more important. Take a look at how Storebrand fares in that regard, below.
Does STB's size influence the expected beta?
Storebrand is a reasonably big company, with a market capitalisation of kr31b. Most companies this size are actively traded with decent volumes of shares changing hands each day. When large companies like this one have a low beta value, there is usually some other factor that is having an outsized impact on the share price. For example, a business with significant fixed regulated assets might earn a reasonably predictable return, regardless of broader macroeconomic factors. Alternatively, lumpy earnings might mean minimal share price correlation with the broader market.
What this means for you:
One potential advantage of owning low beta stocks like Storebrand is that your overall portfolio won't be too sensitive to overall market movements. However, this can be a blessing or a curse, depending on what's happening in the broader market.
