Anyone researching Ocean Bio-Chem, Inc. (NASDAQ:OBCI) might want to consider the historical volatility of the share price. Volatility is considered to be a measure of risk in modern finance theory. Investors may think of volatility as falling into two main categories. 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 are more sensitive to general market forces than others. 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 does OBCI's beta value mean to investors?

Given this level of beta, if the future looks like the past, we could therefore consider it likely that the stock price will experience share price volatility that is roughly similar to the overall market. Beta is worth considering, but it's also important to consider whether Ocean Bio-Chem is growing earnings and revenue. You can take a look for yourself, below.

Could OBCI's size cause it to be more volatile?

Ocean Bio-Chem is a noticeably small company, with a market capitalisation of US$65m. Most companies this size are not always actively traded. Companies this small are usually more volatile than the market, whether or not that volatility is correlated. Therefore, it's a bit surprising to see that this stock has a beta value so close to the overall market.

What this means for you:

It is probable that there is a link between the share price of Ocean Bio-Chem and the broader market, since it has a beta value quite close to one. However, long term investors are generally well served by looking past market volatility and focussing on the underlying development of the business. If that's your game, metrics such as revenue, earnings and cash flow will be more useful. This article aims to educate investors about beta values, but it's well worth looking at important company-specific fundamentals such as Ocean Bio-Chem’s financial health and performance track record.
