How Does Zion Oil & Gas Inc (NASDAQ:ZN) Affect Your Portfolio Returns?

Alvin Rowe

For Zion Oil & Gas Inc’s (NASDAQ:ZN) shareholders, and also potential investors in the stock, understanding how the stock’s risk and return characteristics can impact your portfolio is important. ZN is exposed to market-wide risk, which arises from investing in the stock market. This risk reflects changes in economic and political factors that affects all stocks, and is measured by its beta. Different characteristics of a stock expose it to various levels 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 does ZN’s beta value mean?

Zion Oil & Gas’s beta of 0.15 indicates that the company is less volatile relative to the diversified market portfolio. This means that the change in ZN’s value, whether it goes up or down, will be of a smaller degree than the change in value of the entire stock market index. Based on this beta value, ZN appears to be a stock that an investor with a high-beta portfolio would look for to reduce risk exposure to the market.

Does ZN’s size and industry impact the expected beta?

With a market cap of US$266.98M, ZN falls within the small-cap spectrum of stocks, which are found to experience higher relative risk compared to larger companies. In addition to size, ZN also operates in the oil and gas industry, which has commonly demonstrated strong reactions to market-wide shocks. Therefore, investors may expect high beta associated with small companies, as well as those operating in the oil and gas industry, relative to those more well-established firms in a more defensive industry. It seems as though there is an inconsistency in risks portrayed by ZN’s size and industry relative to its actual beta value. There may be a more fundamental driver which can explain this inconsistency, which we will examine below.

Is ZN’s cost structure indicative of a high beta?

An asset-heavy company tends to have a higher beta because the risk associated with running fixed assets during a downturn is highly expensive. I test ZN’s ratio of fixed assets to total assets in order to determine how high the risk is associated with this type of constraint. Given a fixed to total assets ratio of over 30%, ZN seems to be a company which invests a big chunk of its capital on assets that cannot be scaled down on short-notice. Thus, we can expect ZN to be more volatile in the face of market movements, relative to its peers of similar size but with a lower proportion of fixed assets on their books. However, this is the opposite to what ZN’s actual beta value suggests, which is lower stock volatility relative to the market.

What this means for you:

ZN may be a worthwhile stock to hold onto in order to cushion the impact of a downturn. Depending on the composition of your portfolio, low-beta stocks such as ZN is valuable to lower your risk of market exposure, in particular, during times of economic decline.
