Anyone researching MagnaChip Semiconductor Corporation (NYSE:MX) 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 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 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 greater than one is more sensitive to broader market movements than a stock with a beta of less than one.
What does MX's beta value mean to investors?
As it happens, MagnaChip Semiconductor has a five year beta of 0.92. This is fairly close to 1, so the stock has historically shown a somewhat similar level of volatility as the 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. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall. You can see MagnaChip Semiconductor's revenue and earnings in the image below.
Does MX's size influence the expected beta?
MagnaChip Semiconductor is a rather small company. It has a market capitalisation of US$351m, which means it is probably under the radar of 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 MagnaChip Semiconductor 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.
