If you own shares in Silence Therapeutics plc (LON:SLN) 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. 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 see their prices move in concert with the market. Others tend towards stronger, gentler or unrelated price movements. 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 does SLN's beta value mean to investors?
Zooming in on Silence Therapeutics, we see it has a five year beta of 1.64. This is above 1, so historically its share price has been influenced by the broader volatility of the stock market. If the past is any guide, we would expect that Silence Therapeutics shares will rise quicker than the markets in times of optimism, but fall faster in times of pessimism. Beta is worth considering, but it's also important to consider whether Silence Therapeutics is growing earnings and revenue. You can take a look for yourself, below.
Could SLN's size cause it to be more volatile?
Silence Therapeutics is a noticeably small company, with a market capitalisation of UK£100m. Most companies this size are not always actively traded. It has a relatively high beta, suggesting it is fairly actively traded for a company of its size. Because it takes less capital to move the share price of a small company like this, when a stock this size is actively traded it is quite often more sensitive to market volatility than similar large companies.
What this means for you:
Since Silence Therapeutics 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.
