If you own shares in Sophiris Bio Inc (FRA:BFF1) then it’s worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. Volatility is considered to be a measure of risk in modern finance theory. Investors may think of volatility as falling into two main categories. 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 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 is a widely used metric to measure a stock’s exposure to market risk (volatility). Before we go on, it’s worth noting that Warren Buffett pointed out in his 2014 letter to shareholders that ‘volatility is far from synonymous with risk.’ Having said that, beta can still be rather useful. The first thing to understand about beta is that the beta of the overall market is 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 we can learn from BFF1’s beta value
As it happens, Sophiris Bio has a five year beta of 0.92. This is fairly close to 1, so the stock has historically shown a somewhat similar level of volatility as the market. If the future looks like the past, we could therefore consider it likely that the stock price will experience share price volatility that is roughly similar to the overall market. Beta is worth considering, but it’s also important to consider whether Sophiris Bio is growing earnings and revenue. You can take a look for yourself, below.
How does BFF1’s size impact its beta?
Sophiris Bio is a noticeably small company, with a market capitalisation of €53m. Most companies this size are not always actively traded. It doesn’t take much money to really move the share price of a company as small as this one. That makes it somewhat unusual that it has a beta value so close to the overall market.
What this means for you:
It is probable that there is a link between the share price of Sophiris Bio and the broader market, since it has a beta value quite close to one. However, long term investors are generally well served by looking past market volatility and focussing on the underlying development of the business. If that’s your game, metrics such as revenue, earnings and cash flow will be more useful.
