If you're interested in PolarityTE, Inc. (NASDAQ:PTE), 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 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 are more sensitive to general market forces than others. 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 PTE's beta value mean to investors?
Given that it has a beta of 1.48, we can surmise that the PolarityTE share price has been fairly sensitive to market volatility (over the last 5 years). If this beta value holds true in the future, PolarityTE shares are likely to rise more than the market when the market is going up, but fall faster when the market is going down. Beta is worth considering, but it's also important to consider whether PolarityTE is growing earnings and revenue. You can take a look for yourself, below.
How does PTE's size impact its beta?
With a market capitalisation of US$78m, PolarityTE 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.
What this means for you:
Beta only tells us that the PolarityTE share price is sensitive to broader market movements. This could indicate that it is a high growth company, or is heavily influenced by sentiment because it is speculative. Alternatively, it could have operating leverage in its business model. Ultimately, beta is an interesting metric, but there's plenty more to learn.
