Rockwell Medical, Inc. (NASDAQ:RMTI): What Does Its Beta Value Mean For Your Portfolio?

Jenifer Prater

If you’re interested in Rockwell Medical, Inc. (NASDAQ:RMTI), 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 greater than one is more sensitive to broader market movements than a stock with a beta of less than one.
