Lessons From Nature: The Industry Group Phenomenon

Picture a flock of birds flying perfectly in sync, coordinating their movements as if the collective group were being governed by some invisible hand. Lessons from the natural world can help us understand human behavior. Like animals in nature, stocks tend to move in groups. The company a stock keeps can help us determine which industry groups are leading the market. The majority of past stock market winners were in top industry groups before they went on major runs.

How can we identify which industries are leading the market? Fortunately for investors, our Zacks Industry Rank makes the process simple. Zacks classifies all stocks into one of approximately 250 industry groups based on the Zacks Rank of the individual stocks. The average Zacks Rank is calculated for every industry group each trading day.

We put the Zacks Industry Rank to the test and compared how the top half (industries with the best average Zacks Rank) and the bottom half (industries with the worst average Zacks Rank) fared against the S&P 500. This study was conducted over a ten-year period, and the results speak for themselves.

Over this timeframe, using a one-week rebalance, the top half beat the bottom half by a factor of more than 2 to 1. Clearly, investing in stocks contained within the top industry groups can give investors a leg up on the market.

Let’s take a look at a current example. The Zacks Retail – Convenience Stores industry group is ranked in the top 2% of all Zacks Ranked Industries. This means that more stocks within this industry are experiencing positive earnings estimate revisions, which is at the heart of the Zacks Rank and is the most powerful force impacting stock prices. Below we can see the outperformance of this industry group (green line, +10.78%) versus the iShares Core S&P 500 ETF (black dotted line, -17.21%) year-to-date.

Quantitative research studies have shown that approximately half of a stock’s future price appreciation is due to its industry grouping. By investing in stocks within the best groups, we can provide a constant tailwind to our investing success. Below we will analyze a leading individual stock within this top group.
