If you own shares in I.D. Systems, Inc. (NASDAQ:IDSY) 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. 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 see their prices move in concert with the market. Others tend towards stronger, gentler or unrelated price movements. Beta can be a useful tool to understand how much a stock is influenced by market risk (volatility). However, Warren Buffett said 'volatility is far from synonymous with risk' in his 2014 letter to investors. So, while useful, beta is not the only metric to consider. To use beta as an investor, you must first understand that the overall market has a beta of 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 IDSY's beta value mean to investors?

As it happens, I.D. Systems has a five year beta of 1.04. This is fairly close to 1, so the stock has historically shown a somewhat similar level of volatility as the market. If the future looks like the past, we could therefore consider it likely that the stock price will experience share price volatility that is roughly similar to the overall market. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall. You can see I.D.

Could IDSY's size cause it to be more volatile?

I.D. Systems is a rather small company. It has a market capitalisation of US$105m, which means it is probably under the radar of most investors. It doesn't take much money to really move the share price of a company as small as this one. That makes it somewhat unusual that it has a beta value so close to the overall market.

What this means for you:

I.D. Systems has a beta value quite close to that of the overall market. That doesn't tell us much on its own, so it is probably worth considering whether the company is growing, if you're looking for stocks that will go up more than the overall market. In order to fully understand whether IDSY is a good investment for you, we also need to consider important company-specific fundamentals such as I.D.
