TearLab Corporation (TEAR): How Does It Impact Your Portfolio?

Ajay Mannan

If you are looking to invest in TearLab Corporation’s (NASDAQ:TEAR), or currently own the stock, then you need to understand its beta in order to understand how it can affect the risk of your portfolio. Every stock in the market is exposed to market risk, which arises from macroeconomic factors such as economic growth and geo-political tussles just to name a few. This is measured by its beta. Not every stock is exposed to the same level of market risk, and the broad market index represents a beta value of one. A stock with a beta greater than one is expected to exhibit higher volatility resulting from market-wide shocks compared to one with a beta below one.

What is TEAR’s market risk?

TearLab’s five-year beta of 2.77 means that the company’s value will swing up by more than the market during prosperous times, but also drop down by more in times of downturns. This level of volatility indicates bigger risk for investors who passively invest in the stock market index. Based on this beta value, TEAR will help diversify your portfolio, if it currently comprises of low-beta stocks. This will be beneficial for portfolio returns, in particular, when current market sentiment is positive.

Does TEAR's size and industry impact the expected beta?

TEAR, with its market capitalisation of USD $7.69M, is a small-cap stock, which generally have higher beta than similar companies of larger size. Conversely, the company operates in the healthcare equipment and supplies industry, which has been found to have low sensitivity to market-wide shocks. Therefore, investors can expect a high beta associated with the size of TEAR, but a lower beta given the nature of the industry it operates in. It seems as though there is an inconsistency in risks from TEAR’s size and industry. A potential driver of this variance can be a fundamental factor, which we will take a look at next.

How TEAR's assets could affect its beta

During times of economic downturn, low demand may cause companies to readjust production of their goods and services. It is more difficult for companies to lower their cost, if the majority of these costs are generated by fixed assets. Therefore, this is a type of risk which is associated with higher beta. I test TEAR’s ratio of fixed assets to total assets in order to determine how high the risk is associated with this type of constraint. With a fixed-assets-to-total-assets ratio of greater than 30%, TEAR appears to be a company that invests a large amount of capital in assets that are hard to scale down on short-notice. As a result, this aspect of TEAR indicates a higher beta than a similar size company with a lower portion of fixed assets on their balance sheet. This is consistent with is current beta value which also indicates high volatility.

What this means for you:

Are you a shareholder? You could benefit from higher returns from TEAR during times of economic growth. Its higher fixed cost isn’t a major concern given margins are covered with high consumer demand. However, in times of a downturn, it may be safe to look at a more defensive stock which can cushion the impact of lower demand.

Are you a potential investor? Before you buy TEAR, you should factor how your portfolio currently moves with the wider market, and where we are in the economic cycle. This stock could be an outperformer during times of growth, and it may be worth taking a deeper dive into the fundamentals to crystalize your thoughts on TEAR.
