How Does SigmaTron International, Inc. (NASDAQ:SGMA) Affect Your Portfolio Volatility?

Declan Brown

Anyone researching SigmaTron International, Inc. (NASDAQ:SGMA) might want to consider the historical volatility of the share price. 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 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. 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 SGMA’s beta value

As it happens, SigmaTron International has a five year beta of 1.02. This is fairly close to 1, so the stock has historically shown a somewhat similar level of volatility as the 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. Beta is worth considering, but it’s also important to consider whether SigmaTron International is growing earnings and revenue. You can take a look for yourself, below.

Could SGMA’s size cause it to be more volatile?

With a market capitalisation of US$11m, SigmaTron International 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 SigmaTron International 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.
