Hello all,
Arezi Ratio has published by Elann for many years.

This week,
90-Day Treasury Bill Yield: Approximately 4.25%
S&P 500 Trailing Earnings Yield: Approximately 3.596%
Arezi Ratio = 1.18

Then he used two allocation formulas.

The 'S=120-50*Arezi Ratio' formula indicates an allocation of 61%
stocks, 39% cash this week.

Other timing indicators:
The S&P index is below its 200DMA. - Bearish
We are in the Nov-Apr part of the year. - Bearish
The trailing PE ratio of the S&P is above 17. - Bearish
The treasury yield curve is inverted. - Bullish

A composite allocation may start with the Arezi formula and subtract 10%
for each bearish indicator. The current target allocation is 31%.

Previous studies are here.( what I know)

An alternative allocation, using S=120-30*Arezi Ratio and the first
two of the other timing indicators, produces a target of 64%.

Has anyone done any back testing using these allocation?

Paul
