Anyone researching Aeglea BioTherapeutics, Inc. (NASDAQ:AGLE) might want to consider the historical volatility of the share price. 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 second sort is caused by the natural volatility of markets, overall. For example, certain macroeconomic events will impact (virtually) all stocks on the market.

Some stocks mimic the volatility of the market quite closely, while others demonstrate muted, exagerrated or uncorrelated 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 AGLE's beta value tells investors

As it happens, Aeglea BioTherapeutics 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. 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.

Could AGLE's size cause it to be more volatile?

With a market capitalisation of US$182m, Aeglea BioTherapeutics 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:

It is probable that there is a link between the share price of Aeglea BioTherapeutics 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.
