If you own shares in InterDigital, Inc. (NASDAQ:IDCC) then it's worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. Volatility is considered to be a measure of risk in modern finance theory. Investors may think of volatility as falling into two main categories. 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 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 mimic the volatility of the market quite closely, while others demonstrate muted, exagerrated or uncorrelated 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. 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 does IDCC's beta value mean to investors?
Given this level of beta, 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.

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

What this means for you:
It is probable that there is a link between the share price of InterDigital and the broader market, since it has a beta value quite close to one. However, long term investors are generally well served by looking past market volatility and focussing on the underlying development of the business.
