Hello Zenzi,
I pride myself on responding to almost all of my comments. I'm so sorry that I missed yours!
I am so pleased that you enjoyed the article - it took me several months of work to track down all of these possible alternatives, as well as to wade through the various regulatory suggestions for different measures. Sometimes the level of work to create our articles is invisible (as it should be) to the audience.
I hope that you continue to read The Enterprising Investor and again, my apologies for missing your comment!
Yours, in service,
Jason
