How Does Mersana Therapeutics, Inc. (NASDAQ:MRSN) Affect Your Portfolio Volatility?

If you’re interested in Mersana Therapeutics, Inc. (NASDAQ:MRSN), 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. 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.

Mersana Therapeutics is a noticeably small company, with a market capitalisation of US$149m. 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.
