If you’re interested in Speedcast International Limited (ASX:SDA), 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. 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 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 below one is either less volatile than the market, or more volatile but not corellated with the overall market. In comparison a stock with a beta of over one tends to be move in a similar direction to the market in the long term, but with greater changes in price.
What SDA’s beta value tells investors
Given that it has a beta of 0.83, we can surmise that the Speedcast International share price has not been strongly impacted by broader market volatility (over the last 5 years). This suggests that including it in your portfolio will reduce volatility arising from broader market movements, assuming your portfolio’s weighted average beta is higher than 0.83. 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 Speedcast International fares in that regard, below.
How does SDA’s size impact its beta?
Speedcast International is a small company, but not tiny and little known. It has a market capitalisation of AU$877m, which means it would be on the radar of intstitutional investors. Small companies can have a low beta value when company specific factors outweigh the influence of overall market volatility. That might be happening here.
