Should You Be Concerned About Optical Cable Corporation's (NASDAQ:OCC) Historical Volatility?

If you're interested in Optical Cable Corporation (NASDAQ:OCC), 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. 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 does OCC's beta value mean to investors?

Looking at the last five years, Optical Cable has a beta of 0.87. 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 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 0.87. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall. You can see Optical Cable's revenue and earnings in the image below.

How does OCC's size impact its beta?

Optical Cable is a rather small company. It has a market capitalisation of US$19m, which means it is probably under the radar of most investors. Companies with market capitalisations around this size often show poor correlation with the broader market because market volatility is overshadowed by company specific events, or other factors. It's worth checking to see how often shares are traded, because very small companies with very low beta values are often only thinly traded.

What this means for you:

Since Optical Cable is not heavily influenced by market moves, its share price is probably far more dependent on company specific developments. It could pay to take a closer look at metrics such as revenue growth, earnings growth, and debt. In order to fully understand whether OCC is a good investment for you, we also need to consider important company-specific fundamentals such as Optical Cable’s financial health and performance track record.
