If you're interested in Metro Mining Limited (ASX:MMI), 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 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 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 below one is either less volatile than the market, or more volatile but not corellated with the overall market. In comparison a stock with a beta of over one tends to be move in a similar direction to the market in the long term, but with greater changes in price.
What MMI's beta value tells investors
Looking at the last five years, Metro Mining has a beta of 1.34. The fact that this is well above 1 indicates that its share price movements have shown sensitivity to overall market volatility. Based on this history, investors should be aware that Metro Mining are likely to rise strongly in times of greed, but sell off in times of fear. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall.

Does MMI's size influence the expected beta?
Metro Mining is a rather small company. It has a market capitalisation of AU$180m, which means it is probably under the radar of most investors. Relatively few investors can influence the price of a smaller company, compared to a large company. This could explain the high beta value, in this case.
