Springboro's Traf Dawg team - consisting of seniors Matt Marcus and Matt Clouse - bought 11,000 shares of Mercury Air (MAX) Oct. 4 at $5.20 per share, then sold it later at $8.65.

The team's portfolio was worth a mock $137,364 Thursday at the end of the second week of the game - by far the highest regionally in all age categories.

On Oct. 6, Mercury Air - which provides services to the aviation industry - announced a special cash dividend of $17.5 million, or about $5.45 per share, payable in November.

Springboro fields 44 teams in the game, which gives players a mock $100,000 to invest over 10 weeks. A second Springboro team, Comeback Kids, also capitalized on Mercury Air's run-up and has a portfolio worth $117,692.

"I don't think (Marcus and Clouse) really had any idea'' that stock would jump, said Springboro teacher Rick Creager.

Creager coaches 17 of Springboro's Stock Market Game teams.
