If you're interested in International Zeolite Corp. (CVE:IZ), 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. 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 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 mimic the volatility of the market quite closely, while others demonstrate muted, exagerrated or uncorrelated price movements. Beta is a widely used metric to measure a stock's exposure to market risk (volatility). Before we go on, it's worth noting that Warren Buffett pointed out in his 2014 letter to shareholders that 'volatility is far from synonymous with risk.' Having said that, beta can still be rather useful. The first thing to understand about beta is 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 IZ's beta value tells investors

International Zeolite has a five-year beta of 1.05. This is reasonably close to the market beta of 1, so the stock has in the past displayed similar levels of volatility to the overall market. Using history as a guide, we might surmise that the share price is likely to be influenced by market voltility going forward but it probably won't be particularly sensitive to it. Share price volatility is well worth considering, but most long term investors consider the history of revenue and earnings growth to be more important. Take a look at how International Zeolite fares in that regard, below.

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

International Zeolite is a noticeably small company, with a market capitalisation of CA$2.6m. 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:

International Zeolite has a beta value quite close to that of the overall market. That doesn't tell us much on its own, so it is probably worth considering whether the company is growing, if you're looking for stocks that will go up more than the overall market.
