Diversification  is more important than what
you own or when you own
Methodology:
Diversified buy and hold among un-correlated asset classes.

Forecasts:
Future price/risk relationships based on earnings and price to earnings ratios.

Focus:
Capitalize on benefits of diversification over entire portfolio.

Problem:
The investor must pick the right asset class and the best asset in the class. This method is no help in rapidly declining markets.
