Does Market Volatility Impact MediciNova, Inc.'s (NASDAQ:MNOV) Share Price?

Simply Wall St

Anyone researching MediciNova, Inc. (NASDAQ:MNOV) might want to consider the historical volatility of the share price. Volatility is considered to be a measure of risk in modern finance theory. Investors may think of volatility as falling into two main categories. The first category is company specific volatility. This can be dealt with by limiting your exposure to any particular stock. 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. 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. 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 MNOV's beta value tells investors

Given that it has a beta of 1.27, we can surmise that the MediciNova share price has been fairly sensitive to market volatility (over the last 5 years). If this beta value holds true in the future, MediciNova shares are likely to rise more than the market when the market is going up, but fall faster when the market is going down. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall.

Does MNOV's size influence the expected beta?

With a market capitalisation of US$359m, MediciNova is a very small company by global standards. It is quite likely to be unknown to most investors. Relatively few investors can influence the price of a smaller company, compared to a large company. This could explain the high beta value, in this case.

What this means for you:

Since MediciNova has a reasonably high beta, it's worth considering why it is so heavily influenced by broader market sentiment. For example, it might be a high growth stock or have a lot of operating leverage in its business model. In order to fully understand whether MNOV is a good investment for you, we also need to consider important company-specific fundamentals such as MediciNova’s financial health and performance track record.
