If you own shares in O2Micro International Limited (NASDAQ:OIIM) then it’s worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. Volatility is considered to be a measure of risk in modern finance theory. Investors may think of volatility as falling into two main categories. 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. 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 OIIM’s beta value

Looking at the last five years, O2Micro International has a beta of 0.81. The fact that this is well below 1 indicates that its share price movements haven’t historically been very sensitive to overall market volatility. 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.

Could OIIM’s size cause it to be more volatile?

O2Micro International is a rather small company. It has a market capitalisation of US$41m, which means it is probably under the radar of 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:

Since O2Micro International 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.
