If you're interested in VIVUS, Inc. (NASDAQ:VVUS), then you might want to consider its beta (a measure of share price volatility) in order to understand how the stock could impact your portfolio. Modern finance theory considers volatility to be a measure of risk, and there are two main types of price volatility. The first type is company specific volatility. Investors use diversification across uncorrelated stocks to reduce this kind of price volatility across the portfolio. 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 are more sensitive to general market forces than others. 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 VVUS's beta value tells investors
Looking at the last five years, VIVUS has a beta of 1.67. The fact that this is well above 1 indicates that its share price movements have shown sensitivity to overall market volatility. Based on this history, investors should be aware that VIVUS are likely to rise strongly in times of greed, but sell off in times of fear. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall. You can see VIVUS's revenue and earnings in the image below.

VIVUS is a noticeably small company, with a market capitalisation of US$27m. Most companies this size are not always actively traded. It takes less money to influence the share price of a very small company. This may explain the excess volatility implied by this beta value.
