If you're interested in ENM Holdings Limited (HKG:128), 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. First, we have company specific volatility, which is the price gyrations of an individual stock. Holding at least 8 stocks can reduce this kind of risk across a portfolio. 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 see their prices move in concert with the market. Others tend towards stronger, gentler or unrelated price movements. Beta is a widely used metric to measure a stock's exposure to market risk (volatility). Before we go on, it's worth noting that Warren Buffett pointed out in his 2014 letter to shareholders that 'volatility is far from synonymous with risk.' Having said that, beta can still be rather useful. The first thing to understand about beta is 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 128's beta value tells investors

With a beta of 1.05, (which is quite close to 1) the share price of ENM Holdings has historically been about as voltile as the broader market. If the future looks like the past, we could therefore consider it likely that the stock price will experience share price volatility that is roughly similar to the overall market. Beta is worth considering, but it's also important to consider whether ENM Holdings is growing earnings and revenue. You can take a look for yourself, below.

Does 128's size influence the expected beta?

ENM Holdings is a rather small company. It has a market capitalisation of HK$1.2b, which means it is probably under the radar of most investors. It doesn't take much money to really move the share price of a company as small as this one. That makes it somewhat unusual that it has a beta value so close to the overall market.

What this means for you:

Since ENM Holdings has a beta close to one, it will probably show a positive return when the market is moving up, based on history. If you're trying to generate better returns than the market, it would be worth thinking about other metrics such as cashflows, dividends and revenue growth might be a more useful guide to the future. In order to fully understand whether 128 is a good investment for you, we also need to consider important company-specific fundamentals such as ENM Holdings’s financial health and performance track record.
