Does Ardelyx, Inc. (NASDAQ:ARDX) Have A Volatile Share Price?

If you own shares in Ardelyx, Inc. (NASDAQ:ARDX) then it’s worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. 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 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 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. 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.

Does ARDX’s size influence the expected beta?

Ardelyx is a noticeably small company, with a market capitalisation of US$366m. Most companies this size are not always actively traded. 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:

Since Ardelyx has a reasonably high beta, it’s worth considering why it is so heavily influenced by broader market sentiment.
