How Does Zai Lab Limited (NASDAQ:ZLAB) Affect Your Portfolio Volatility?

Simply Wall St

Anyone researching Zai Lab Limited (NASDAQ:ZLAB) might want to consider the historical volatility of the share price. Volatility is considered to be a measure of risk in modern finance theory. Investors may think of volatility as falling into two main categories. 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. 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 ZLAB's beta value tells investors

Zooming in on Zai Lab, we see it has a five year beta of 1.39. This is above 1, so historically its share price has been influenced by the broader volatility of the stock market. If this beta value holds true in the future, Zai Lab shares are likely to rise more than the market when the market is going up, but fall faster when the market is going down. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall.

How does ZLAB's size impact its beta?

Zai Lab is a reasonably big company, with a market capitalisation of US$2.7b. Most companies this size are actively traded with decent volumes of shares changing hands each day. It takes deep pocketed investors to influence the share price of a large company, so it's a little unusual to see companies this size with high beta values. It may be that that this company is more heavily impacted by broader economic factors than most.

What this means for you:

Beta only tells us that the Zai Lab share price is sensitive to broader market movements. This could indicate that it is a high growth company, or is heavily influenced by sentiment because it is speculative. Alternatively, it could have operating leverage in its business model. Ultimately, beta is an interesting metric, but there's plenty more to learn.
