If you own shares in Luna Innovations Incorporated (NASDAQ:LUNA) then it’s worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. Volatility is considered to be a measure of risk in modern finance theory. Investors may think of volatility as falling into two main categories. 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 mimic the volatility of the market quite closely, while others demonstrate muted, exagerrated or uncorrelated price movements. Beta can be a useful tool to understand how much a stock is influenced by market risk (volatility). However, Warren Buffett said ‘volatility is far from synonymous with risk’ in his 2014 letter to investors. So, while useful, beta is not the only metric to consider. To use beta as an investor, you must first understand that the overall market has a beta of 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 LUNA’s beta value
Given that it has a beta of 0.83, we can surmise that the Luna Innovations share price has not been strongly impacted by broader market volatility (over the last 5 years). If history is a good guide, owning the stock should help ensure that your portfolio is not overly sensitive to market volatility. 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 Luna Innovations’s revenue and earnings in the image below.
Does LUNA’s size influence the expected beta?
Luna Innovations is a rather small company. It has a market capitalisation of US$82m, which means it is probably under the radar of most investors. It is not unusual for very small companies to have a low beta value, especially if only low volumes of shares are traded. Even when they are traded more actively, the share price is often more susceptible to company specific developments than overall market volatility.
What this means for you:
Since Luna Innovations 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 LUNA is a good investment for you, we also need to consider important company-specific fundamentals such as Luna Innovations’s financial health and performance track record.
