If you own shares in Aqua Metals, Inc. (NASDAQ:AQMS) 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. 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. 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.
What AQMS's beta value tells investors
As it happens, Aqua Metals has a five year beta of 0.95. This is fairly close to 1, so the stock has historically shown a somewhat similar level of volatility as the market. While history does not always repeat, this may indicate that the stock price will continue to be exposed to market risk, albeit not overly so. 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 Aqua Metals fares in that regard, below.
Does AQMS's size influence the expected beta?
With a market capitalisation of US$104m, Aqua Metals is a very small company by global standards. It is quite likely to be unknown to most investors. 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:
Since Aqua Metals has a beta close to one, it will probably show a positive return when the market is moving up, based on history. If you're trying to generate better returns than the market, it would be worth thinking about other metrics such as cashflows, dividends and revenue growth might be a more useful guide to the future.
