Below is the income statement of a publicly-traded biotech company from 2004 until 2007:
| 
 Year  | 
 2004  | 
 2005  | 
 2006  | 
 2007  | 
| 
 Revenue  | 
 $0  | 
 $0  | 
 $0  | 
 $0  | 
| 
 Expenses  | 
 $0.2 million  | 
 $0.7 million  | 
 $2.2 million  | 
 $4.8 million  | 
The company’s stock was trading for $2 in 2004 and is now trading for $7. Are investors irrational? Should the stock be sold short? Is it possible for a company in the biotech business to be worth something even though it has no current sales? What can justify the billion-dollar values of technology companies which have yet to earn any profits?
