Anyone researching Nanosonics Limited (ASX:NAN) 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 mimic the volatility of the market quite closely, while others demonstrate muted, exagerrated or uncorrelated price movements. Beta can be a useful tool to understand how much a stock is influenced by market risk (volatility). However, Warren Buffett said 'volatility is far from synonymous with risk' in his 2014 letter to investors. So, while useful, beta is not the only metric to consider. To use beta as an investor, you must first understand that the overall market has a beta of 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 we can learn from NAN's beta value
Given that it has a beta of 1.30, we can surmise that the Nanosonics share price has been fairly sensitive to market volatility (over the last 5 years). If this beta value holds true in the future, Nanosonics shares are likely to rise more than the market when the market is going up, but fall faster when the market is going down. Share price volatility is well worth considering, but most long term investors consider the history of revenue and earnings growth to be more important. Take a look at how Nanosonics fares in that regard, below.
How does NAN's size impact its beta?
Nanosonics is a small cap stock with a market capitalisation of AU$2.0b. Most companies this size are actively traded. 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 Nanosonics 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.
