If you own shares in Cardno Limited (ASX:CDD) 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 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. 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 we can learn from CDD's beta value
Zooming in on Cardno, we see it has a five year beta of 0.89. 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). Beta is worth considering, but it's also important to consider whether Cardno is growing earnings and revenue. You can take a look for yourself, below.
Could CDD's size cause it to be more volatile?
With a market capitalisation of AU$355m, Cardno is a very small company by global standards. It is quite likely to be unknown to most investors. It is not unusual for very small companies to have a low beta value, especially if only low volumes of shares are traded. Even when they are traded more actively, the share price is often more susceptible to company specific developments than overall market volatility.
What this means for you:
One potential advantage of owning low beta stocks like Cardno 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.
