FYI: Once upon a time, portfolios were constructed via story-telling. Once built, they were marketed via data.
Our understanding of how returns are generated has changed in the past two decades, which in turn has led to a change in ways the financial industry assembles, manages and markets investments.
In broad terms, the paradigm has been flipped on its head: Portfolios now are carefully constructed based on data and marketed by way of narrative story-telling.
