One Thing To Remember About The Lexicon Pharmaceuticals, Inc. (NASDAQ:LXRX) Share Price

If you own shares in Lexicon Pharmaceuticals, Inc. (NASDAQ:LXRX) 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 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. 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.

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

Small companies can have a low beta value when company specific factors outweigh the influence of overall market volatility. That might be happening here.

What this means for you:

The Lexicon Pharmaceuticals 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.
