If you own shares in China Renewable Energy Investment Limited (HKG:987) then it’s worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. 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. 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 we can learn from 987’s beta value
China Renewable Energy Investment has a five-year beta of 1.03. This is reasonably close to the market beta of 1, so the stock has in the past displayed similar levels of volatility to the overall market. While history does not always repeat, this may indicate that the stock price will continue to be exposed to market risk, albeit not overly so. 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 China Renewable Energy Investment fares in that regard, below.
How does 987’s size impact its beta?
China Renewable Energy Investment is a rather small company. It has a market capitalisation of HK$571.4m, which means it is probably under the radar of most investors. Companies this small are usually more volatile than the market, whether or not that volatility is correlated. Therefore, it’s a bit surprising to see that this stock has a beta value so close to the overall market.
What this means for you:
It is probable that there is a link between the share price of China Renewable Energy Investment and the broader market, since it has a beta value quite close to one. However, long term investors are generally well served by looking past market volatility and focussing on the underlying development of the business. If that’s your game, metrics such as revenue, earnings and cash flow will be more useful. This article aims to educate investors about beta values, but it’s well worth looking at important company-specific fundamentals such as China Renewable Energy Investment’s financial health and performance track record.
