How Does Investing In Greenhill & Co., Inc. (NYSE:GHL) Impact The Volatility Of Your Portfolio?
Anyone researching Greenhill & Co., Inc. (NYSE:GHL) 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 type is company specific volatility. Investors use diversification across uncorrelated stocks to reduce this kind of price volatility across the 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 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. 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 GHL's beta value tells investors
Zooming in on Greenhill, we see it has a five year beta of 0.88. This is below 1, so historically its share price has been rather independent from the market. This means that -- if history is a guide -- buying the stock would reduce the impact of overall market volatility in many portfolios (depending on the beta of the portfolio, of course). 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 Greenhill fares in that regard, below.
Does GHL's size influence the expected beta?
With a market capitalisation of US$328m, Greenhill is a very small company by global standards. It is quite likely to be unknown to most investors. Companies with market capitalisations around this size often show poor correlation with the broader market because market volatility is overshadowed by company specific events, or other factors. It's worth checking to see how often shares are traded, because very small companies with very low beta values are often only thinly traded.
What this means for you:
One potential advantage of owning low beta stocks like Greenhill is that your overall portfolio won't be too sensitive to overall market movements. However, this can be a blessing or a curse, depending on what's happening in the broader market.
