Throughout his two classic investment primers, he has outlined many of the investments he found when not in his office. For example, in One Up Lynch explains how he invested in Dunkin' Donuts not after reading about the company in The Wall Street Journal, but after being impressed by their coffee as a customer. Assuming others would be similarly impressed and noting the company's Boston locations were always busy, he then studied the company's financial status and decided to invest in Dunkin' Donuts, which proved one of the best-performing stocks he ever bought. Lynch believes the individual investor is able to make similar smart investing choices noticing particular opportunities like Dunkin' Donuts or paying attention to business trends in their careers and hobbies. Using examples from Magellan Fund, his books outline how a novice should read and interpret company paperwork for information on stock valuation, earnings, cash flow, and other data. Lynch has stated in One Up on Wall Street that his undergraduate studies in philosophy and logic were more important to his career than the math or finance he studied for his MBA. At Wharton, he came to believe that the two prevailing investing theories in academia, the random walk hypothesis and the efficient market hypothesis, were contradictory. The concepts taught by professors at school were regularly disproved by professionals during his internship at Fidelity. He thus came to rely more on practitioners than theoreticians: "It seemed to me that what was supposed to help you succeed in the investment business, could only help you fail ... Quantitative analysis taught me that the things I saw happening at Fidelity couldn't really be happening." Lynch has also argued against market timing, stating: "Far more money has been lost by investors preparing for corrections or trying to anticipate corrections than has been lost in the corrections themselves." Lynch popularized the stock investment strategy “GARP” (Growth At A Reasonable Price), which is a hybrid stock-picking approach that balances Growth investing potential for share-price increases with the discipline of Value investing to avoid buying overpriced stocks. Many well-known funds now follow the GARP model, ranging from equity funds such as Fidelity Investments Fidelity Contrafund (FCNTX) and Lemma Senbet Fund, to index funds such as Russell Indexes iShares Russell 1000 Growth Index. He also coined the phrase "ten bagger" in a financial context. This refers to an investment which is worth ten times its
