One Thing To Remember About The Alimera Sciences, Inc. (NASDAQ:ALIM) Share Price

Simply Wall St

Anyone researching Alimera Sciences, Inc. (NASDAQ:ALIM) 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 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. 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. 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 ALIM's beta value tells investors

Given that it has a beta of 1.91, we can surmise that the Alimera Sciences share price has been fairly sensitive to market volatility (over the last 5 years). Based on this history, investors should be aware that Alimera Sciences are likely to rise strongly in times of greed, but sell off in times of fear. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall.

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

Alimera Sciences is a rather small company. It has a market capitalisation of US$21m, which means it is probably under the radar of most investors. It takes less money to influence the share price of a very small company. This may explain the excess volatility implied by this beta value.

What this means for you:
