PortfolioPerfection,
Not sure, this market timing question to me or Chris.
i am using both price and EPS downtrend in my designer model market timing.
- 
in the chart unemployment, 1930 to 1952 it goes up and down 
 market was flat or in downtrend, employment rate is controlled by federal.
- 
interest rate is 0-1% controlled by federal for last 10 years, market was in up. 
- 
$TNX yield, controlled by federal was down for last 15 years. 
Stock Price and company Earnings belongs to company prospects can’t be controlled.
I have learned these stuffs from Fred Richard, AAII Dallas chapter, president. who claims he observed federal data for last 55 years in OUT OF SAMPLE   . he not able to make any money on federal/economic data.
 . he not able to make any money on federal/economic data.
One more myths, investing in benchmark/index will return 6% return over 20+  years period; it is not always true.
from 1929 to 1952,
0% return for 23 years investment in indexes.
Thanks
Kumar
