If you're interested in ShareRoot Limited (ASX:SRO), 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. First, we have company specific volatility, which is the price gyrations of an individual stock. Holding at least 8 stocks can reduce this kind of risk across a 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. 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 below one is either less volatile than the market, or more volatile but not corellated with the overall market. In comparison a stock with a beta of over one tends to be move in a similar direction to the market in the long term, but with greater changes in price.

What does SRO's beta value mean to investors?
Zooming in on ShareRoot, we see it has a five year beta of 1.13. This is above 1, so historically its share price has been influenced by the broader volatility of the stock market.

Could SRO's size cause it to be more volatile?
ShareRoot is a rather small company. It has a market capitalisation of AU$2.9m, which means it is probably under the radar of most investors. 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.
What this means for you:
Since ShareRoot has a reasonably high beta, it's worth considering why it is so heavily influenced by broader market sentiment. For example, it might be a high growth stock or have a lot of operating leverage in its business model.
