If you own shares in Alpha and Omega Semiconductor Limited (NASDAQ:AOSL) then it's worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. Volatility is considered to be a measure of risk in modern finance theory. Investors may think of volatility as falling into two main categories. The first category is company specific volatility. This can be dealt with by limiting your exposure to any particular stock. 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. 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. 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 AOSL's beta value tells investors
Zooming in on Alpha and Omega Semiconductor, we see it has a five year beta of 0.80. This is below 1, so historically its share price has been rather independent from the market. This means that -- if history is a guide -- buying the stock would reduce the impact of overall market volatility in many portfolios (depending on the beta of the portfolio, of course). 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 Alpha and Omega Semiconductor fares in that regard, below.
How does AOSL's size impact its beta?
Alpha and Omega Semiconductor is a noticeably small company, with a market capitalisation of US$278m. Most companies this size are not always actively traded. 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:
Since Alpha and Omega Semiconductor is not heavily influenced by market moves, its share price is probably far more dependend on company specific developments. It could pay to take a closer look at metrics such as revenue growth, earnings growth, and debt.
