If you own shares in IVERIC bio, Inc. (NASDAQ:ISEE) 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 type is company specific volatility. Investors use diversification across uncorrelated stocks to reduce this kind of price volatility across the 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 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 greater than one is more sensitive to broader market movements than a stock with a beta of less than one.

What we can learn from ISEE's beta value
Looking at the last five years, IVERIC bio has a beta of 1.47. The fact that this is well above 1 indicates that its share price movements have shown sensitivity to overall market volatility. If this beta value holds true in the future, IVERIC bio shares are likely to rise more than the market when the market is going up, but fall faster when the market is going down. Beta is worth considering, but it's also important to consider whether IVERIC bio is growing earnings and revenue. You can take a look for yourself, below.
How does ISEE's size impact its beta?
IVERIC bio is a noticeably small company, with a market capitalisation of US$58m. Most companies this size are not always actively traded. 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:
Beta only tells us that the IVERIC bio 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. Ultimately, beta is an interesting metric, but there's plenty more to learn.
