How ATOSS Software AG (ETR:AOF) Can Impact Your Portfolio Volatility

In This Article:

If you own shares in ATOSS Software AG (ETR:AOF) then it's worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. Modern finance theory considers volatility to be a measure of risk, and there are two main types of price volatility. The first category is company specific volatility. This can be dealt with by limiting your exposure to any particular stock. The second type is the broader market volatility, which you cannot diversify away, since it arises from macroeconomic factors which directly affects all the stocks on the market.

Some stocks are more sensitive to general market forces than others. 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 AOF's beta value

Looking at the last five years, ATOSS Software has a beta of 0.84. The fact that this is well below 1 indicates that its share price movements haven't historically been very sensitive to overall market volatility. This means that -- if history is a guide -- buying the stock would reduce the impact of overall market volatility in many portfolios (depending on the beta of the portfolio, of course). Beta is worth considering, but it's also important to consider whether ATOSS Software is growing earnings and revenue. You can take a look for yourself, below.

Does AOF's size influence the expected beta?

ATOSS Software is a small cap stock with a market capitalisation of €493m. Most companies this size are actively traded. Small companies can have a low beta value when company specific factors outweigh the influence of overall market volatility. That might be happening here.

What this means for you:

The ATOSS Software doesn't usually show much sensitivity to the broader market. This could be for a variety of reasons. Typically, smaller companies have a low beta if their share price tends to move a lot due to company specific developments. Alternatively, an strong dividend payer might move less than the market because investors are valuing it for its income stream.
