If you own shares in Amkor Technology, Inc. (NASDAQ:AMKR) 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 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 mimic the volatility of the market quite closely, while others demonstrate muted, exagerrated or uncorrelated 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. 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 AMKR's beta value
Looking at the last five years, Amkor Technology has a beta of 1.99. The fact that this is well above 1 indicates that its share price movements have shown sensitivity to overall market volatility. Based on this history, investors should be aware that Amkor Technology are likely to rise strongly in times of greed, but sell off in times of fear. Share price volatility is well worth considering, but most long term investors consider the history of revenue and earnings growth to be more important. Take a look at how Amkor Technology fares in that regard, below.
Does AMKR's size influence the expected beta?
With a market capitalisation of US$1.8b, Amkor Technology is a small cap stock. However, it is big enough to catch the attention of professional investors. It's not particularly surprising that it has a higher beta than the overall market. That's because it takes less money to influence the share price of a smaller company, than a bigger company.
What this means for you:
Since Amkor Technology has a reasonably high beta, it's worth considering why it is so heavily influenced by broader market sentiment. For example, it might be a high growth stock or have a lot of operating leverage in its business model.
