SMI stock plummets

Speedway Motorsports stock have lost more than half their value over the past year, with the stock price dropping from about $40 last July to just above $18 Monday. Even in today's bear market, that's a big slide. By comparison, the S&P 500 Index and other major market measures are down about 20 percent, while shares in International Speedway Corp. – Speedway Motorsports' chief rival – are down almost 30 percent from a year ago. Both speedway owners have been tested by an economic downtown that has curbed fan attendance and spending.
