Does anyone recall how Robert Lichello came up with the term 'twinvest'?
One of life's mysteries, I think. I do know he used all caps for it TWINVEST. Such is often the case with an acronym, such as AIM for Automatic Investment Management. He'd previously used the term "Synchrovest," so obviously needed some sort of new name. The VEST part refers to investing, that's easy enough. TWIN may have come from it being a near "twin" to Synchrovest, but it's only a guess. I skimmed the chapter and, unless I missed it, he gives us the name for the technique - but not the why of the name.
Maybe someone else will have a better insight...
Best,
