Value Averaging: The Safe and Easy Strategy for Higher Investment Returns

All these books are worth reading! Lucile Tomlinson has some interesting comments about both the Constant Dollar Plan and Dollar cost averaging.
Robert Lichello, in his Two books appears to have addressed theses comments with his simple formula's.
Mr. Edleson, in his book talks about his concerns with Dollar cost averaging. He talks about how it does not take into account Inflation or Growth of the stock market. He addresses this in his chapter on growth DCA. In his chapter on Value Averaging he combines his ideals on growth DCA with the Constant Dollar Plan, such that instead of a constant dollar amount, you use a changing dollar amount as a target that you buy or sell shares to meet.
It's my thinking that these different ideals could be combined into a better formula. Not sure how as of yet.
Come see me at Systematic Investing group #board-966 lets talk formula plans.
