One Thing To Remember About The BJ's Restaurants, Inc. (NASDAQ:BJRI) Share Price

Simply Wall St

If you're interested in BJ's Restaurants, Inc. (NASDAQ:BJRI), 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. 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 second sort is caused by the natural volatility of markets, overall. For example, certain macroeconomic events will impact (virtually) all stocks on the market.

Some stocks see their prices move in concert with the market. Others tend towards stronger, gentler or unrelated price movements. 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.

What does BJRI's beta value mean to investors?

Given that it has a beta of 0.88, we can surmise that the BJ's Restaurants share price has not been strongly impacted by broader market volatility (over the last 5 years). This means that -- if history is a guide -- buying the stock would reduce the impact of overall market volatility in many portfolios (depending on the beta of the portfolio, of course). Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall.

Does BJRI's size influence the expected beta?

BJ's Restaurants is a small cap stock with a market capitalisation of US$740m. Most companies this size are actively traded. Small companies can have a low beta value when company specific factors outweigh the influence of overall market volatility. That might be happening here.
