Philip A. Fisher Collected Works Quotes

“Conversely, as such a stock rises to, say, 50 or 60 or 70, the urge to sell and take a profit now that the stock is “high” becomes irresistible to many people. Giving in to this urge can be very costly. This is because the genuinely worthwhile profits in stock investing have come from holding the surprisingly large number of stocks that have gone up many times from their original cost. The only true test of whether a stock is “cheap” or “high” is not its current price in relation to some former price, no matter how accustomed we may have become to that former price, but whether the company’s fundamentals are significantly more or less favorable than the current financial-community appraisal of that stock.”

“But recognizing changes in public taste and then reacting promptly to these changes is not enough. As has been said before, in the business world customers simply do not beat a path to the door of the man with the better mousetrap. In the competitive world of commerce it is vital to make the potential customer aware of the advantages of a product or service. This awareness can be created only by understanding what the potential buyer really wants (sometimes when the customer himself doesn’t clearly recognize why these advantages appeal to him) and explaining it to him not in the seller’s terms but in his terms.”
