If you're interested in Advanced Energy Industries, Inc. (NASDAQ:AEIS), then you might want to consider its beta (a measure of share price volatility) in order to understand how the stock could impact your portfolio. 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 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 mimic the volatility of the market quite closely, while others demonstrate muted, exagerrated or uncorrelated price movements. Beta is a widely used metric to measure a stock's exposure to market risk (volatility). Before we go on, it's worth noting that Warren Buffett pointed out in his 2014 letter to shareholders that 'volatility is far from synonymous with risk.' Having said that, beta can still be rather useful. The first thing to understand about beta is that the beta of the overall market is 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 AEIS's beta value tells investors
Given that it has a beta of 1.51, we can surmise that the Advanced Energy Industries share price has been fairly sensitive to market volatility (over the last 5 years). If this beta value holds true in the future, Advanced Energy Industries shares are likely to rise more than the market when the market is going up, but fall faster when the market is going down. 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 Advanced Energy Industries fares in that regard, below.
How does AEIS's size impact its beta?
Advanced Energy Industries is a small company, but not tiny and little known. It has a market capitalisation of US$1.9b, which means it would be on the radar of intstitutional investors. It has a relatively high beta, which is not unusual among small-cap stocks. Because it takes less capital to move the share price of a smaller company, actively traded small-cap stocks often have a higher beta that a similar large-cap stock.
What this means for you:
Beta only tells us that the Advanced Energy Industries share price is sensitive to broader market movements. This could indicate that it is a high growth company, or is heavily influenced by sentiment because it is speculative. Alternatively, it could have operating leverage in its business model.
