Nick Caldari, a junior at North Shore High School in Glen Head, won first place statewide at the high school level of InvestWrite, a national financial writing competition administered by The Stock Market Game.
"Death of the Hamburglar," his 800- word essay, keyed off a fictional event: the effect a surgeon general's warning about the dangers of eating ground beef could have on stocks of McDonald's and Chipotle Mexican Grill.
"McDonald's would probably go out of business, and Chipotle would do well," said Caldari, 17. Of his interest in the stock market, he said: "It's cool to see how different aspects of the world can affect stock prices."
About 1,600 high school students submitted essays this year, the school district said. Essays were judged on understanding of the subject matter, rationale and writing style.
For winning, Caldari received a surprise visit last month from The Stock Market Game's "prize patrol" and will receive a trophy and a $100 gift card at an award ceremony this summer.
At school he is secretary of the Future Business Leaders of America and a member of the Key Club, the National Honor Society and the soccer team.
