Aldeyra Therapeutics Inc (ALDX): How Does It Impact Your Portfolio?

If you are looking to invest in Aldeyra Therapeutics Inc’s (NASDAQ:ALDX), 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 all stocks are expose to the same level of market risk, and the market as a whole represents a beta value of one. A stock with a beta greater than one is considered more sensitive to market-wide shocks compared to a stock that trades below the value of one.

What does ALDX's beta value mean?

With a five-year beta of 0.37, Aldeyra Therapeutics appears to be a less volatile company compared to the rest of the market. The stock will exhibit muted movements in both the downside and upside, in response to changing economic conditions, whereas the general market may move by a lot more. ALDX's beta implies it may be a stock that investors with high-beta portfolios might find relevant if they wanted to reduce their exposure to market risk, especially during times of downturns.

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

With a market cap of USD $137.65M, ALDX falls within the small-cap spectrum of stocks, which are found to experience higher relative risk compared to larger companies. However, ALDX operates in the biotechnology industry, which has commonly demonstrated muted reactions to market-wide shocks. As a result, we should expect a high beta for the small-cap ALDX but a low beta for the biotechnology industry. It seems as though there is an inconsistency in risks from ALDX’s size and industry. A potential driver of this variance can be a fundamental factor, which we will take a look at next.

Is ALDX's cost structure indicative of a high 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 ALDX’s ratio of fixed assets to total assets in order to determine how high the risk is associated with this type of constraint. Since ALDX’s fixed assets are only 0.18% of its total assets, it doesn’t depend heavily on a high level of these rigid and costly assets to operate its business. Thus, we can expect ALDX to be more stable in the face of market movements, relative to its peers of similar size but with a higher portion of fixed assets on their books. Similarly, ALDX’s beta value conveys the same message.

What this means for you:

Are you a shareholder? You could benefit from lower risk during times of economic decline by holding onto ALDX. Its low fixed cost also means that, in terms of operating leverage, it is relatively flexible during times of economic downturns. Consider the stock in terms of your other portfolio holdings, and whether it is worth investing more into ALDX.

Are you a potential investor? You should consider the stock in terms of your portfolio. It could be a valuable addition in times of an economic decline, due to its low fixed cost and low beta. However, I recommend you to also look at its fundamental factors as well, such as its current valuation and financial health to assess its investment thesis in further detail.
