HERE is a book of which it can truly be said that the cost of not reading it may be beyond your means. All you have to ask yourself to decide that point in advance is whether you are satisfied with your investment record; or whether you recall with a shudder the times you have bought securities near the highs of their cyclical price ranges, or sold some near the lows. Formula plans are to investor's emotions what governors are to engines devices to keep both from running away with themselves. Bull markets result when avarice overcomes fear. Bear markets come about when conditions are the opposite. Formula plans in one way or another compel their adherents to act on the principle that half a loaf is better than no bread before the dominant speculative emotion changes. _________________ Miss Tomlinson ends her discussion of this ultra simple investment formula with the striking sentence: "No one has yet discovered any other formula for investing which can be used with so much confidence of ultimate success, regardless of what may happen to security prices, as Dollar Cost Averaging."
