MBA students Yoshi Matsuzawa (above) and Erin Quinn (below) impressed the judges on CNBC's Fast Money.

Georgia Tech MBA students Erin Quinn and Yoshi Matsuzawa recently appeared on different episodes of CNBC's Fast Money show, earning high grades for their trading decisions in stock-market scenarios.

Fast Money typically features several MBA students from top business schools on its "Grade the Trade" segment each Friday. Both Quinn and Matsuzawa earned A- grades from the show's experts (scoring higher than the students from other schools featured in those episodes: Emory University, Boston University, and Georgetown University).

Quinn had to decide what stocks to trade in the scenario of oil hitting $80 a barrel. She said she would buy stocks in alternative energy (i.e. solar), Toyota for its hybrid technology, and an exchange traded fund tracking energy stocks. She would sell stocks in travel-related businesses like airlines and rental car companies.

For his scenario, Matsuzawa chose what to trade if Advanced Micro Devices and Intel had announced major price cuts to win market share. He would sell the chip sector and buy PC makers of cheaper computers. He liked Hewlett Packard, Microsoft, MEMC Electronics, and other electronic companies.

Students featured on Fast Money appear via Webcam so they don't have to travel to the show's New York studio. But Quinn was already in New York, where she's interning this summer at Credit Suisse, so she visited the studio for her appearance. Matsuzawa appeared live from the Management building. They had three hours to research their answers before filming began.

Though confident about her stock recommendations, Quinn says she felt the "traditional heart-pounding fear" before going on TV. Therefore, she appreciated the encouragement she got from the College of Management's business communications instructor Spring Asher to "be a star" and have "big energy!"
