What Kind Of Share Price Volatility Should You Expect For The Medicines Company (NASDAQ:MDCO)?

Simply Wall St

Anyone researching The Medicines Company ( NASDAQ:MDCO ) might want to consider the historical volatility of the share price. 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 other type, which cannot be diversified away, is the volatility of the entire market. Every stock in the market is exposed to this volatility, which is linked to the fact that stocks prices are correlated in an efficient market.

Some stocks mimic the volatility of the market quite closely, while others demonstrate muted, exagerrated or uncorrelated 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. Any stock with a beta of greater than one is considered more volatile than the market, while those with a beta below one are either less volatile or poorly correlated with the market.

What does MDCO's beta value mean to investors?

Given that it has a beta of 1.35, we can surmise that the Medicines share price has been fairly sensitive to market volatility (over the last 5 years). If this beta value holds true in the future, Medicines shares are likely to rise more than the market when the market is going up, but fall faster when the market is going down. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall.

Does MDCO's size influence the expected beta?

With a market capitalisation of US$2.4b, Medicines is a pretty big company, even by global standards. It is quite likely well known to very many investors. It takes a lot of money to influence the share price of large companies like this one. That makes it interesting to note that its share price has a history of sensitivity to market volatility. There might be some aspect of the business that means profits are leveraged to the economic cycle.

What this means for you:

Beta only tells us that the Medicines share price is sensitive to broader market movements. This could indicate that it is a high growth company, or is heavily influenced by sentiment because it is speculative. Alternatively, it could have operating leverage in its business model. Ultimately, beta is an interesting metric, but there's plenty more to learn. In order to fully understand whether MDCO is a good investment for you, we also need to consider important company-specific fundamentals such as Medicines’s financial health and performance track record.
