Anyone researching Luminex Corporation (NASDAQ:LMNX) might want to consider the historical volatility of the share price. 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 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 mimic the volatility of the market quite closely, while others demonstrate muted, exagerrated or uncorrelated 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. 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 LMNX’s beta value mean to investors?
Given that it has a beta of 0.82, we can surmise that the Luminex share price has not been strongly impacted by broader market volatility (over the last 5 years). 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 0.82. 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 Luminex’s revenue and earnings in the image below.
Could LMNX’s size cause it to be more volatile?
With a market capitalisation of US$1.2b, Luminex is a small cap stock. However, it is big enough to catch the attention of professional investors. Small companies can have a low beta value when company specific factors outweigh the influence of overall market volatility. That might be happening here.
What this means for you:
Since Luminex is not heavily influenced by market moves, its share price is probably far more dependend 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 LMNX is a good investment for you, we also need to consider important company-specific fundamentals such as Luminex’s financial health and performance track record.
