Shiller pe  strategy  (from www.myplaniq.com)
 

------------------------------------------------------
based  on the ratio of the current CAPE10 to the long term average CAPE10:
§  Significantly Overvalued (SO): such as if the ratio >=150%
§  Modestly Overvalued (MO): such as if   117%<=  ratio < 150%
§  Fairly Valued (FV): such as if 83% <= ratio < 117%
§  Modestly Undervalued (MU): such as if 67% <= ratio< 83%
§  Significantly Undervalued (SU): such as if ratio < 67%

These  five categories are determined by four valuation parameters (such as 150%,117%, 83% and 67% in the above). At each rebalancing (adjusting) period (suchas weekly or monthly), the strategy decides at what region the US stock market   valuation is and then does the following rebalancing:
§  SO: 0% in stock, 100% in cash.
§  MO: 25% in stock, 75% in cash.
§  FV: 50% in stock, 50% in cash
§  MU: 75% in stock, 25% in cash
§  SU: 100% in stock, 0% in cash
