@DividendGrowth: These are the Dividend Achieve...

These are the Dividend Achievers from 1992 with the highest Return on Equity (ROE)

The companies on that list are still around. However, many of them have also been acquired.

Do you think high ROE could be a sign of a competitive advantage

This is a list of the 1997 Dividend Achievers with the highest ROE h/t @BrandonVanZee

I see a similar theme here

Note:

These lists are from the 1992 and 1997 Moody's Dividend Achievers Handbooks

I may post lists from other years, as I find them
