One Thing To Consider Before Buying O2Micro International Limited (OIIM)

If you are looking to invest in O2Micro International Limited’s (NASDAQ:OIIM), or currently own the stock, then you need to understand its beta in order to understand how it can affect the risk of your portfolio. Every stock in the market is exposed to market risk, which arises from macroeconomic factors such as economic growth and geo-political tussles just to name a few. This is measured by its beta. Not every stock is exposed to the same level of market risk, and the broad market index represents a beta value of one. A stock with a beta greater than one is considered more sensitive to market-wide shocks compared to a stock that trades below the value of one.

What does OIIM's beta value mean?

With a five-year beta of 0.15, O2Micro International appears to be a less volatile company compared to the rest of the market. This means the stock is more defensive against the ups and downs of a stock market, moving by less than the entire market index in times of change. OIIM’s beta indicates it is a stock that investors may find valuable if they want to reduce the overall market risk exposure of their stock portfolio.

Does OIIM's size and industry impact the expected beta?

A market capitalisation of USD $45.74M puts OIIM in the category of small-cap stocks, which tends to possess higher beta than larger companies. Furthermore, the company operates in the semiconductors and semiconductor equipment industry, which has been found to have high sensitivity to market-wide shocks. Therefore, investors may expect high beta associated with small companies, as well as those operating in the semiconductors and semiconductor equipment industry, relative to those more well-established firms in a more defensive industry. It seems as though there is an inconsistency in risks portrayed by OIIM’s size and industry relative to its actual beta value. A potential driver of this variance can be a fundamental factor, which we will take a look at next.

Is OIIM's cost structure indicative of a high beta?

An asset-heavy company tends to have a higher beta because the risk associated with running fixed assets during a downturn is highly expensive. I test OIIM’s ratio of fixed assets to total assets in order to determine how high the risk is associated with this type of constraint. Since OIIM’s fixed assets are only 27.20% of its total assets, it doesn’t depend heavily on a high level of these rigid and costly assets to operate its business. As a result, the company may be less volatile relative to broad market movements, compared to a company of similar size but higher proportion of fixed assets. Similarly, OIIM’s beta value conveys the same message.

What this means for you:

Are you a shareholder? You may reap the benefit of muted movements during times of economic decline by holding onto OIIM. Its low fixed cost also means that, in terms of operating leverage, its costs are relatively malleable to preserve margins. I recommend analysing the stock in terms of your current portfolio composition before increasing your exposure to the stock.

Are you a potential investor? You should consider the stock in terms of your portfolio. It could be a valuable addition in times of an economic decline, due to its low fixed cost and low beta. However, I recommend you to also look at its fundamental factors as well, such as its current valuation and financial health to assess its investment thesis in further detail.

Beta is one aspect of your portfolio construction to consider when holding or entering into a stock. But it is certainly not the only factor.
