How ImmunoGen Inc (NASDAQ:IMGN) Can Impact Your Portfolio Volatility

Anyone researching ImmunoGen Inc (NASDAQ:IMGN) 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 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 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.

Share price volatility is well worth considering, but most long term investors consider the history of revenue and earnings growth to be more important. Take a look at how ImmunoGen fares in that regard, below.

It has a relatively high beta, which is not unusual among small-cap stocks. Because it takes less capital to move the share price of a smaller company, actively traded small-cap stocks often have a higher beta that a similar large-cap stock.
