If you own shares in IRadimed Corporation (NASDAQ:IRMD) then it's worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. Modern finance theory considers volatility to be a measure of risk, and there are two main types of price volatility. 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 see their prices move in concert with the market. Others tend towards stronger, gentler or unrelated 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 greater than one is more sensitive to broader market movements than a stock with a beta of less than one.
What does IRMD's beta value mean to investors?
Given that it has a beta of 1.65, we can surmise that the IRadimed share price has been fairly sensitive to market volatility (over the last 5 years). If the past is any guide, we would expect that IRadimed shares will rise quicker than the markets in times of optimism, but fall faster in times of pessimism. Beta is worth considering, but it's also important to consider whether IRadimed is growing earnings and revenue. You can take a look for yourself, below.
Could IRMD's size cause it to be more volatile?
With a market capitalisation of US$239m, IRadimed is a very small company by global standards. It is quite likely to be unknown to most investors. 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.
