Anyone researching NCC Limited (NSE:NCC) 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 see their prices move in concert with the market. Others tend towards stronger, gentler or unrelated 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 NCC's beta value tells investors

Beta is worth considering, but it's also important to consider whether NCC is growing earnings and revenue. You can take a look for yourself, below.

Does NCC's size influence the expected beta?

With a market capitalisation of ₹35b, NCC is a very small company by global standards. It is quite likely to be unknown to most investors. It is not unusual for very small companies to have a low beta value, especially if only low volumes of shares are traded. Even when they are traded more actively, the share price is often more susceptible to company specific developments than overall market volatility.

What this means for you:

One potential advantage of owning low beta stocks like NCC is that your overall portfolio won't be too sensitive to overall market movements. However, this can be a blessing or a curse, depending on what's happening in the broader market. In order to fully understand whether NCC is a good investment for you, we also need to consider important company-specific fundamentals such as NCC’s financial health and performance track record.
