Does Market Volatility Impact Amphastar Pharmaceuticals, Inc.’s (NASDAQ:AMPH) Share Price?

Simply Wall St

If you own shares in Amphastar Pharmaceuticals, Inc. (NASDAQ:AMPH) 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. 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 see their prices move in concert with the market. Others tend towards stronger, gentler or unrelated 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.

Could AMPH’s size cause it to be more volatile?

With a market capitalisation of US$1.1b, Amphastar Pharmaceuticals is a small cap stock. However, it is big enough to catch the attention of professional investors. It is quite common to see a small-cap stock with a beta greater than one. In part, that’s because relatively few investors can influence the price of a smaller company, compared to a large company.
