Episode notes

One of the biggest problems with calculators like this is they try to mix and match predictable things with unpredictable things. If you're trying to get to something that is very precise, because what you really want to model there is a range of outcomes. But it's not going to get you to the Holy Grail principle where you are looking at the correlations and the diversification within asset classes which is important for portfolio construction.

In this episode we answer questions from Shplendid Spencer, Russel and MyContactInfo. We discuss the pros and cons of online calculators and how they are commonly inadequate and/or misused, why being conservative beyond realistic possibilities is probably not a good idea overall, and an article by Aswath Damodaran about Nvidia, the chip industry and the implications of AI for DIY investing. CORRECTION: I said the Heat Map calculator was at Portfolio Visualizer -- it's actually at Portfolio Charts at the link below.

And THEN we our go through our weekly portfolio reviews of the seven sample portfolios you can find at Portfolios | Risk Parity Radio.
