Taking the “Industrial” out of the title would go a long way to making me happy.
Obviously it was way easier back in the day to track just 40 companies. Today, it seem way too arbitrary. As the times have changed, the index should cover a higher number of enterprises. [Why stick with 40? - makes no sense]
I agree. Keeping it to 40 companies does not seem realistic today with all the diversity in our economy. Back in the 1920s, nobody could imagine that gigantic corporations would emerge from such things as streaming video (Netflix), fast food (Chik-Fil-A), home delivery (Amazon), and car rides (Uber), just to name a few.
