How Kirby Corporation (NYSE:KEX) Can Impact Your Portfolio Volatility

If you own shares in Kirby Corporation (NYSE:KEX) 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 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 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 greater than one is more sensitive to broader market movements than a stock with a beta of less than one.

Does KEX’s size influence the expected beta?

Kirby is a reasonably big company, with a market capitalisation of US$4.5b. Most companies this size are actively traded with decent volumes of shares changing hands each day. We shouldn’t be surprised to see a large company like this with a beta value quite close to the market average. Large companies often move roughly in line with the market. In part, that’s because there are fewer individual events that are signficant enough to markedly change the value of the stock (compared to small companies, at least).

What this means for you:

Since Kirby has a beta close to one, it will probably show a positive return when the market is moving up, based on history. If you’re trying to generate better returns than the market, it would be worth thinking about other metrics such as cashflows, dividends and revenue growth might be a more useful guide to the future.
