If you're interested in China Automotive Systems, Inc. (NASDAQ:CAAS), 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 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. 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 CAAS's beta value tells investors
Looking at the last five years, China Automotive Systems has a beta of 1.81. The fact that this is well above 1 indicates that its share price movements have shown sensitivity to overall market volatility. If the past is any guide, we would expect that China Automotive Systems shares will rise quicker than the markets in times of optimism, but fall faster in times of pessimism. 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 Automotive Systems fares in that regard, below.
Could CAAS's size cause it to be more volatile?
China Automotive Systems is a rather small company. It has a market capitalisation of US$108m, 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.
What this means for you:
Beta only tells us that the China Automotive Systems share price is sensitive to broader market movements. This could indicate that it is a high growth company, or is heavily influenced by sentiment because it is speculative. Alternatively, it could have operating leverage in its business model. Ultimately, beta is an interesting metric, but there's plenty more to learn.
