In brief 

Kenneth Fisher is a high profile investment manager and one of the richest people in America. He is credited with establishing the price-to-sales ratio as a hugely influential indicator in the valuation of stocks.

He explains: “Very few investors have a rational basis for valuing growth stocks in the face of a lack of earnings. The stock loses supporters and falls, in time, much too far. The best managements react to difficulties and overcome them. In time, sales pick up. Later, profits begin to pick up. Simultaneously with the profit resurgence, the stock price begins to rebound.”
