Bangalore: At the age of Seventeen most of us did not have the slightest clue of what a stock market is or how it works. What investments were or what the Wall Street was meant for. An age, when most adolescents are into books busy studying Physics, Chemistry and Maths, John Wang Clow made it into history by becoming 'The youngest licensed stock broker in the world.' John Wang Clow was 17 years and 44 days old when he passed the Investment Banking Examination (Series 79) administered by The Financial Industry Regulatory Authority (FINRA). John has created a new Guinness World Record after beating Jason A. Earle of Princeton from New Jersey, who earned his stockbroker license in 1993 at age 17 years, 206 days. The Series 79 is an administered examination conducted by the Financial Regulatory Authority which tests the skills of aspiring investment bankers on Mergers and Acquisitions, buyouts, public investment banking and refinancing. The exam is considered as one of the longest FINRA-administered exams which have about 175 questions plus un-scored questions given over a period of five hours. The paper consists of 4 areas - Collection, Analysis and Evaluation of Data; Underwriting/New Financing Transactions; Mergers and Acquisitions; and General Securities Regulations. After two months of intense preparation, Clow scored 82 percent. Clow studies at a boarding school in New Hampshire and during his summer holidays he decided to take a summer job at his own father's financial firm, The Hina Group. "If you don't understand economics and business, you can't understand how this capitalist economy works," he said. "So I thought that through this, I'd have the opportunity to learn."
