Does American Shared Hospital Services (NYSEMKT:AMS) Have A High Beta?

Simply Wall St

Anyone researching American Shared Hospital Services (NYSEMKT:AMS) 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. The first category is company specific volatility. This can be dealt with by limiting your exposure to any particular stock. 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 are more sensitive to general market forces than others. Some investors use beta as a measure of how much a certain stock is impacted by market risk (volatility). While we should keep in mind that Warren Buffett has cautioned that 'Volatility is far from synonymous with risk', beta is still a useful factor to consider. To make good use of it you must first know 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.

Does AMS's size influence the expected beta?

American Shared Hospital Services is a rather small company. It has a market capitalisation of US$14m, which means it is probably under the radar of most investors. Very small companies often have a low beta value because their share prices are not well correlated with market volatility. This could be because the price is reacting to company specific events. Alternatively, the shares may not be actively traded.

What this means for you:

One potential advantage of owning low beta stocks like American Shared Hospital Services is that your overall portfolio won't be too sensitive to overall market movements.
