What You Must Know About MainStreet Bancshares, Inc.'s (NASDAQ:MNSB) Beta Value

Simply Wall St

Anyone researching MainStreet Bancshares, Inc. (NASDAQ:MNSB) 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 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. A stock with a beta below one is either less volatile than the market, or more volatile but not corellated with the overall market. In comparison a stock with a beta of over one tends to be move in a similar direction to the market in the long term, but with greater changes in price.

What MNSB's beta value tells investors

Given that it has a beta of 0.82, we can surmise that the MainStreet Bancshares share price has not been strongly impacted by broader market volatility (over the last 5 years).

Beta is worth considering, but it's also important to consider whether MainStreet Bancshares is growing earnings and revenue. You can take a look for yourself, below.

Does MNSB's size influence the expected beta?

With a market capitalisation of US$189m, MainStreet Bancshares is a very small company by global standards. It is quite likely to be unknown to 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:

The MainStreet Bancshares doesn't usually show much sensitivity to the broader market. This could be for a variety of reasons. Typically, smaller companies have a low beta if their share price tends to move a lot due to company specific developments. Alternatively, an strong dividend payer might move less than the market because investors are valuing it for its income stream.
