Anyone researching China Display Optoelectronics Technology Holdings Limited (HKG:334) 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 type is the broader market volatility, which you cannot diversify away, since it arises from macroeconomic factors which directly affects all the 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 greater than one is more sensitive to broader market movements than a stock with a beta of less than one.
What we can learn from 334's beta value
China Display Optoelectronics Technology Holdings has a five-year beta of 1.08. 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. Using history as a guide, we might surmise that the share price is likely to be influenced by market voltility going forward but it probably won't be particularly sensitive to it. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall.

Could 334's size cause it to be more volatile?
With a market capitalisation of HK$1.1b, China Display Optoelectronics Technology Holdings is a very small company by global standards. It is quite likely to be unknown to 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 Display Optoelectronics Technology Holdings 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.
