Debate Club Round 2: Risk, Rationality, and Efficiency

Welcome Back Debate Fans!

Are you ready for Grumpus to grumble about the concept of investing the Emergency Fund (EF) in equities?

Or should I say “GGGGGRRRRUUUUMMMMBBBLLLLEEE” in my best sport’s announcer’s voice?

Yes, I know. You’re wondering how, with only two readers who aren’t related to me, did I gain any publicity? Well, it turns out I have a face built for radio — or podcasting as the case may be.  Not so sure about the voice though.

In any case, on a recent (and so far my only) podcast interview on ChooseFI, the hosts asked me to explain my concept of the Gap Number. For those of you who need a refresher on the Gap Number, you can find the post where I coined the term here. In general, the Gap Number is the difference between your fixed income in retirement and your expenses. Expressed mathematically it looks like: Continue reading
