If you own shares in Empire State Realty Trust, Inc. (NYSE:ESRT) 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 category is company specific volatility. This can be dealt with by limiting your exposure to any particular stock. 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 mimic the volatility of the market quite closely, while others demonstrate muted, exagerrated or uncorrelated 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. 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 we can learn from ESRT's beta value
Empire State Realty Trust has a five-year beta of 0.95. This is reasonably close to the market beta of 1, so the stock has in the past displayed similar levels of volatility to the overall market. Using history as a guide, we might surmise that the share price is likely to be influenced by market voltility going forward but it probably won't be particularly sensitive to it. Share price volatility is well worth considering, but most long term investors consider the history of revenue and earnings growth to be more important. Take a look at how Empire State Realty Trust fares in that regard, below.
Does ESRT's size influence the expected beta?
With a market capitalisation of US$4.8b, Empire State Realty Trust is a pretty big company, even by global standards. It is quite likely well known to very many investors. It's not overly surprising to see large companies with beta values reasonably close to the market average. After all, large companies make up a higher weighting of the index than do small companies.
What this means for you:
It is probable that there is a link between the share price of Empire State Realty Trust 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. If that's your game, metrics such as revenue, earnings and cash flow will be more useful.
