Anyone researching Cardiovascular Systems, Inc. (NASDAQ:CSII) 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 type is company specific volatility. Investors use diversification across uncorrelated stocks to reduce this kind of price volatility across the portfolio. 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 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 does CSII's beta value mean to investors?
Given that it has a beta of 1.69, we can surmise that the Cardiovascular Systems share price has been fairly sensitive to market volatility (over the last 5 years). Based on this history, investors should be aware that Cardiovascular Systems are likely to rise strongly in times of greed, but sell off in times of fear. Beta is worth considering, but it's also important to consider whether Cardiovascular Systems is growing earnings and revenue. You can take a look for yourself, below.
How does CSII's size impact its beta?
Cardiovascular Systems is a small company, but not tiny and little known. It has a market capitalisation of US$1.6b, which means it would be on the radar of intstitutional investors. It is quite common to see a small-cap stock with a beta greater than one. In part, that's because relatively few investors can influence the price of a smaller company, compared to a large company.
What this means for you:
