Hi Toof, I'm no expert on indicators and economics, but just from experience of AIMin for several years I think there is something missing from the v wave. I can't put my finger on it, whether it's the difference between stock and cash yields, interest rates, available liquidity, other factors or combination of these I think the v wave misses the mark. We've been scaling it to try to improve it but I think it's more than an issue of scaling, it does not take into account enough information about the market and the situation.
Personally I think if you have a reasonable portfolio, diversified with multiple ETFs, a cash reserve of 20-25% is sufficient even at this time. I recall that Tom's I-wave was a much better indicator and was a combination of multiple factors.
