Dimerix Limited (ASX:DXB): What Does Its Beta Value Mean For Your Portfolio?

If you're interested in Dimerix Limited (ASX:DXB), 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. The first category is company specific volatility. This can be dealt with by limiting your exposure to any particular stock. 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 are more sensitive to general market forces than others. 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 below one is either less volatile than the market, or more volatile but not corellated with the overall market. In comparison a stock with a beta of over one tends to be move in a similar direction to the market in the long term, but with greater changes in price.

What we can learn from DXB's beta value

Given that it has a beta of 1.63, we can surmise that the Dimerix share price has been fairly sensitive to market volatility (over the last 5 years). If the past is any guide, we would expect that Dimerix shares will rise quicker than the markets in times of optimism, but fall faster in times of pessimism. 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 Dimerix fares in that regard, below.

Does DXB's size influence the expected beta?

Dimerix is a noticeably small company, with a market capitalisation of AU$16m. Most companies this size are not always actively traded. It has a relatively high beta, suggesting it is fairly actively traded for a company of its size. Because it takes less capital to move the share price of a small company like this, when a stock this size is actively traded it is quite often more sensitive to market volatility than similar large companies.
