A month or so ago, I started to seriously ponder the concept of exploring uniting the two concepts; namely to attempt to build a top-quality dividend producing portfolio from a manageable number of individual stocks, using the world's best dividend ETFs to help me find them.Why might this approach be worthy of your consideration? Well, let's say you want to add some top-quality dividend paying companies to your portfolio. One approach would be to attempt to find these stocks on your own. You could start with a review of the research section on your brokerage's website. From there, you could then pore over analyst reports, weighing various companies one against the other. Wait a minute, though. Might there be an easier approach?In this article I just finished for Seeking Alpha, I posit that there might be. Using the cumulative selection criteria utilized by five world-class dividend-growth and high-dividend-yield ETFs, I select what the math argues are perhaps the 12 best stocks to include in your dividend portfolio. I also include a variant that adds an additional 3 stocks, for a total of 15.Take a look, and let me know what you think!
