Hey DS, been following a bit of the discussion in the gold thread, and it's been stated quite a few times that are a few of the posters, yourself included, use gold as a kind of insurance protection for your portfolios. Whilst if I was going to calculate how much insurance I needed for my house or car, it would appear pretty easy to do. However, permanent risks to an investment portfolio are obviously much harder, or even impossible, to quantify. What sort of methods do you know that estimate how much portfolio insurance you may need?
This is an imperfect hedge. I call it a jelly hedge. We are using a cross-hedge. For the scenarios being insured, there really is no choice as a standard put option would not insure the assets in extreme situations.
The degree of insurance provided will need to be estimated using either/or/all of:
+ scenario based methods informed by observation of long history;
+ checking movements of markets for the most extreme movements...tail hedge delta;
+ making a guess with your best judgment. I would use a delta like -0.5 for working purposes. In other words, in a run-of-the-mill disaster, a 50% fall in equities due to disorderly inflation would see a 25% increase in the price of gold. But this will vary by scenario. In the very extreme scenario of destruction of productive assets and abandonment of currency due to war, that delta can move towards infinity.
I am not seeking to fully insure this scenario. I acknowledge that the chances are not zero and seek to make allowance for it, however imperfectly calculated.
