What's Up With Tyco?

The Exeter, New Hampshire-based company Tyco International took another hit today at the stock market.

Tyco was the most active big board stock dropping 6 dollars 80 cents or nearly 23%.

That follows yesterday's 19% plunge.

Karin Thorburn is a finance professor at Dartmouth's Tuck School of Business.

She tells NHPR's Mark Bevis that Tyco is facing several problems all at the same time.
