If you're interested in Sleep Number Corporation (NASDAQ:SNBR), 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. 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 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 SNBR's beta value mean to investors?
Zooming in on Sleep Number, we see it has a five year beta of 1.14. This is above 1, so historically its share price has been influenced by the broader volatility of the stock market. Based on this history, investors should be aware that Sleep Number 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 Sleep Number's revenue and earnings in the image below.
Does SNBR's size influence the expected beta?
Sleep Number is a small company, but not tiny and little known. It has a market capitalisation of US$1.1b, 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:
Since Sleep Number tends to moves up when the market is going up, and down when it's going down, potential investors may wish to reflect on the overall market, when considering the stock.
