How GigaMedia Limited (NASDAQ:GIGM) Can Impact Your Portfolio Volatility

Liz Campbell

If you own shares in GigaMedia Limited (NASDAQ:GIGM) then it’s worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. 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 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 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.

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

GigaMedia is a noticeably small company, with a market capitalisation of US$31m. Most companies this size are not always actively traded. 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:

GigaMedia has a beta value quite close to that of the overall market. That doesn’t tell us much on its own, so it is probably worth considering whether the company is growing, if you’re looking for stocks that will go up more than the overall market. This article aims to educate investors about beta values, but it’s well worth looking at important company-specific fundamentals such as GigaMedia’s financial health and performance track record.
