The latest edition of the annual FORTUNE 100 Best Companies to Work For list affirms once again that great workplaces benefit from stronger financial performance, reduced turnover and better customer and patient satisfaction than their peers. Produced in collaboration with research and consulting firm Great Place to Work®, the annual list is based on the most extensive employee survey in corporate America. Anonymous input from 315,000 employees on leader quality, support for professional and personal lives and colleague relationships comprise a Trust Index to compare organizations against peers. The companies that make the list are known for their employee satisfaction but, importantly, generate strong business performance year after year.
The outperformance is notable. Global index provider FTSE Russell – which annually analyzes the FORTUNE 100 Best Companies to Work For list – this year found that an equally-weighted index of the publicly-traded companies among the 100 best returned 11.66% annually from 1998 through the end of 2016, nearly 5% more than the equivalent returns for the benchmark US all-cap Russell 3000® Index (6.72%) and US large cap Russell 1000® Index (6.68%). How can an index outperform the market by 5% over nearly 20 years? We believe this can be attributed to art and science.
First, the art. A wide body of research and evidence supports the fact that engaged employees make for happy and successful companies. Caring and high-trust company cultures with a sense of purpose and clarity are consistently associated with strong revenue and stock performance. In their forthcoming book, A Great Place to Work For All, CEO Michael C. Bush and the research team of Great Place to Work argue that leading companies are racing ahead because they bring out the best in every employee, regardless of who they are or what they do for the organization. “Business success relies on developing all your human potential,” Bush and his co-authors write. “Every employee matters in an economy that is about connectivity, innovation, and human qualities like passion, character, and collaboration.”
Great Place to Work’s new methodology—baked into the rankings for this year’s FORTUNE 100 Best Companies to Work For list—rewards companies that create a consistently great culture across demographic groups and job levels. Bush and crew also have documented business advantages such as revenue outperformance for these new “Great Place to Work For All.” The way the 2017 Best Companies to Work For tap everyone’s potential may explain the bump in stock performance this past year (see chart below).
The idea that “when companies take care of employees, employees take care of the business” isn’t new and may seem obvious to some. But as the FORTUNE 100 Best Companies to Work For show, it can play a critical role in performance. Don’t underestimate the power of culture.
Next, the science. When FTSE Russell creates its index of the publicly traded FORTUNE 100 Best Companies to Work For, it has a stellar crop of companies to measure. And the “100 Best Index,” a hypothetical index created by FTSE Russell specifically for FORTUNE and Great Place to Work, is updated each year based on last year’s winners, ensuring it is continually refreshed with strong companies. Yet FTSE Russell takes its analysis a step further by equal weighting and quarterly rebalancing this hypothetical portfolio. Through equal weighting, all constituents are assigned the same index weight, regardless of market capitalization, to ensure that the largest companies don’t have an outsized impact on index performance. Quarterly rebalancing is a way to systematically reweight the index to adjust for market performance.
Equal weighting with systematic rebalancing has historically delivered strong relative returns over time. In fact, in the case of the 100 Best Index, when FTSE Russell performed an attribution analysis to determine the source of excess return for the 100 Best Index over the broad market, 80% of the excess return was due to the selection of the 100 Best companies but an additional 20% can be attributed to the equal weighting and quarterly rebalancing methodology of the 100 Best Index.
Investors can benefit from this simple formula. Bring together the art of recognizing cultures that are great for all their people, as well as the science of smart portfolio construction.
