If you own shares in Urban Tea, Inc. (NASDAQ:MYT) 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 type is the broader market volatility, which you cannot diversify away, since it arises from macroeconomic factors which directly affects all the 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 is a widely used metric to measure a stock's exposure to market risk (volatility). Before we go on, it's worth noting that Warren Buffett pointed out in his 2014 letter to shareholders that 'volatility is far from synonymous with risk.' Having said that, beta can still be rather useful. The first thing to understand about beta is that the beta of the overall market is one. A stock with a beta greater than one is more sensitive to broader market movements than a stock with a beta of less than one.

What we can learn from MYT's beta value

Looking at the last five years, Urban Tea has a beta of 1.80. The fact that this is well above 1 indicates that its share price movements have shown sensitivity to overall market volatility. If this beta value holds true in the future, Urban Tea 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.

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

Urban Tea is a rather small company. It has a market capitalisation of US$22m, which means it is probably under the radar of most investors. Relatively few investors can influence the price of a smaller company, compared to a large company. This could explain the high beta value, in this case.

What this means for you:

Beta only tells us that the Urban Tea 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.
