If you're interested in Hanwei Energy Services Corp. (TSE:HE), 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. Volatility is considered to be a measure of risk in modern finance theory. Investors may think of volatility as falling into two main categories. The first type is company specific volatility. Investors use diversification across uncorrelated stocks to reduce this kind of price volatility across the 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. Some investors use beta as a measure of how much a certain stock is impacted by market risk (volatility). While we should keep in mind that Warren Buffett has cautioned that 'Volatility is far from synonymous with risk', beta is still a useful factor to consider. To make good use of it you must first know 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 HE's beta value tells investors
Looking at the last five years, Hanwei Energy Services has a beta of 1.31. 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 Hanwei Energy Services 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 HE's size influence the expected beta?
Hanwei Energy Services is a rather small company. It has a market capitalisation of CA$4.9m, which means it is probably under the radar of most investors. It takes less money to influence the share price of a very small company. This may explain the excess volatility implied by this beta value.
