Is SemGroup Corporation (NYSE:SEMG) A Volatile Stock?

Simply Wall St

Anyone researching SemGroup Corporation (NYSE:SEMG) 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. 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 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.

Beta is worth considering, but it's also important to consider whether SemGroup is growing earnings and revenue. You can take a look for yourself, below.

Could SEMG's size cause it to be more volatile?

SemGroup is a small company, but not tiny and little known. It has a market capitalisation of US$1.1b, which means it would be on the radar of intstitutional investors. It is quite common to see a small-cap stock with a beta greater than one. In part, that's because relatively few investors can influence the price of a smaller company, compared to a large company.

What this means for you:
